If I know I must wake up at a certain time I get so anxious and nervous that I can't sleep the night before. I get very sick from not sleeping. I have been to doctors and take medicine for sleep. But just knowing I need to get up for fajr or any other reason like some appointment I can't sleep all night.
The only way I can deal with this is to allow myself sleep without setting an alarm clock and making up fajr whenever I get up.
I feel very guilty about this. I have tried going back to sleep after fajr or trying to take a nap later in the day but it doesn't work. Once I am awake for the day I can't fall back asleep no matter how bad I feel. I have tried to overcome this but I just can't. I'm not lazy. Its a medical issue. I just have this terrible insomnia. I've had this insomnia since I was a child. I've had it for over 40 years. All of you are blessed who can get a good nights sleep and wake up for fajr after resting well. I wish I could do it. So is it all right to make up fajr whenever I get up? I thank you for taking the time to read and answer my question. Asalaamu alaykum
