It's 3.20am and I'm drinking as much water as I can.
Two litres if I can manage.
I now need to get to sleep so I get at least five hours sleep to get me through a day in work.
The trouble is I'll wake up at least twice before my 8.30am alarm because I'll need the toilet so badly.
Plus my stomach is so full of water it's just bloated. So I can't sleep.
But if I don't drink before bed I'm going to pass out in the daytime.
When I wake up I won't be able to eat or drink for 18 hours.
I'm writing this at the start of Ramadan, the holiest month in the Islamic calendar, which comes around once a year.
It means Muslims who are fit and able have to fast between sunrise and sunset hours.
It is held during the ninth month of the Islamic calendar and is a time for spiritual reflection and charity.
Fasting is also one of the five pillars of Islam so it is an important part in the life of a Muslim.
It is physically demanding and emotionally exhausting.
People think that not eating is the hard part, but the lack of sleep is worse.
It doesn't just impact my mood but my productivity. I have to make sure it does not impact on relationships and on my job.
Beginning the fast
Muslims begin the fast with a meal known as Suhoor which is before sunrise.
This means waking up in the middle of the night and eating and drinking enough to keep you going.
The hardest thing is forcing yourself to eat a bowl of porridge and drink at least a litre of water.
Most days I'd have have toast, eggs, yoghurt, dates and water. Sometimes I would have cereal and a smoothie.
The best foods to eat are those with slow releasing energy, there's a long day ahead.
The first day of Ramadan saw me start my fast at 3.50am.
But it's summer, the days become longer, the sun rises earlier. By the end of the month I have to finish eating by 3am.
The first few days are the toughest as your body ajusts. Your sleeping pattern is all over the place and it's hard to get used to not eating and drinking.
After eating food and coping with what I call "water belly" it's time for morning prayer, known as Fajr, before going back to bed and trying to get a few hours of sleep before work.
Working while fasting
I have fasted for more than 12 years but having started my first full-time job in journalism last year this is the first time I have been working and fasting.
I am thankful to my boss for allowing me to change my working hours and to start work later so I can have some sleep.
Starting the day is actually the toughest part, getting up after four or five hours of sleep.
I cut my lunch hour in half because what's the point of sitting there eating nothing.
And doing nothing just makes me tired, I'd rather keep my brain active.
Even if I feel tired or agitated, I don't show it in the workplace or around friends or colleagues who are not Muslims.
I don't expect others to change their lives around mine so I tell them it's fine to talk about food or to eat in front of me - although many of them have been really considerate about doing that.
Mood throughout the day
Fasting is more of a mental strain than a physical thing. You must understand why you are fasting and the purpose behind it.
I remind myself why I'm doing it at moments of weakness. It's the best way of getting through it.
I actually feel privileged to be able to go without food and drink for so many hours. Because I but I'll have food at home and a roof over my head each night.
Reminding myself of that is part of the mental strength gets through the long hours of fasting.
At times, I get tired and agitated as the day goes on.
The hot weather doesn't help. It makes you more thirsty. And more tired.
I'm happy when I get up and it's cloudy and miserable.
When I'm fasting it's also a reminder how much caffeine i normally consume.
I usually drink tea or coffee in the morning and cutting it out doesn't help my mood. In fact cutting out caffeine causes me headaches throughout the day.
I constantly think about having a hot drink at 10pm after the sun has gone down - even though I know caffeine is the last thing you need before a short night of sleep.
I don't smoke but some Muslims do and they can't smoke during fasting. Nothing can go into the body.
What does the fast consist of?
The fast consists of the five obligatory prayers and a number of voluntary prayers throughout the day.
The Qur'an is also recited in this month as Muslims believe it was in this month the Qur'an was revealed to the prophet Muhammad.
Donating to charity is also encouraged and Muslims will donate millions to charity in this month and also spend hours volunteering.
The fasting does get easier after the first week as you get in to a routine and your body gets used to the lack of food.
The evening meal
The fast breaks at 8.47pm but gets later in the month due to the daylight hours increasing.
By the end of the month I was breaking my fast at almost 9.30pm.
This is tough of course and the wait can be long and draining, but I ensured I kept myself busy with prayer and work to ensure the day wasn't dragging and I made myself productive.
The trouble is you might think I would eat a feast of food but my stomach shrinks throughout the month and after a few bites I feel full.
Eating is bitter sweet. You've been thinking about it all day, and it's over so quickly. And you don't feel that satisfied at times. Just bloated.
For Iftaar I get together with my family and everyone breaks their fast together. We usually have a date and some water together. It's symbolic to do that as a family.
This is the main reason why Ramadan is my favourite month of the year as everyone eats at the same time and family spirit is usually high.
Food for Iftaar varies and I will usually have foods such as samosas, roast chicken, curries, salads and vegetables.
Mosques across the UK open their doors for people to open their fast for free.
Hundreds of people, Muslims and non Muslims will break their fast at Mosques and this is important for those without family living locally.
After food it is time for the final prayer of the night, known as Taraweeh. It is a voluntary prayer where parts of the Qur'an are recited every day, with the aim of completing the Qur'an by the end of the month.
This starts at around 10.30pm and ends after midnight and can be tiring, but is my favourite part of the month. The feeling of seeing family and friends at the mosque, all there for the same reason, is very inspiring.
Eid is celebrated at the end of Ramadan and marks the end of fasting for ramadan. It is celebrated with a special prayer in the morning.
I gather with my family later in the day and enjoy a feast with presents and money.
Money is also donated to charity as well as food.
Why Ramadan is such an important month
Many people will wonder why me and 1.8 billion Muslims across the world fast. Some may even see it as cruel and tough.
But Ramadan is a month where worship is entirely between me and God.
I could easily break my fast in the day and no one would know, but it's important to stick to your beliefs and understand why you are fasting. Fasting helps appreciate your blessings and builds empathy for the poor people across the world.
Ramadan is hard, no one said it was easy. It challenges my patience, strength and determination. Going without food and drink for so many hours is tough and it always feels like the hours are slowing down.
But this is where you learn a lot about yourself and about your mental strength.
Ramadan means different things to everyone, but the main lessons are patience, forgiveness, strength and compassion.
Fasting also has amazing physical benefits which I definitely feel at the end of the month. My body and mind feel a lot stronger as does my mental strength.
It has also inspired me to fast two days a week every week to retain the benefits of fasting.
