Is this something from Satan

Aoa since Ramadan ended, I've struggled with tahajjud snd fajar prayers. To resolve the issue i started going to bed early.lets say the fajar is at 530, so i goto bed at 10. With my alarm set for 430. But every night، i wakeup at around 2 am and struggle to fall back asleep until the alarm rings..at that point I'm so drowsy and exhausted that i cant offer my prayers..even though i get out to turn of alarm placed far away..

Is this from satan? Or what? Do we have a psychiatrist in this group?
