should i stay up on every non-school night, up until fajr, so i can pray fajr and not miss it? because my medication makes me sleepy, and my doctor doesn't want to lower the dosage right away, (but she is planning on lowering the dosage of my risperdal, but only gradually), and I have a hard time getting up in the mornings for fajr except on school days when my mother wakes me up....tomorrow is sunday, where i live, and it is saturday night, so should i stay up all night so i can pray fajr? my father warned me not to do this because he says that ill get my sleeping schedule messed up, and ill end up missing school my oversleeping....
