For as long as I can remember (even dating back to childhood) ive never had a consistent ability to maintain a sleep time. This has resulted in me always being tired. I remember in elementary school over the summer I’d fall asleep at 4am and wake up at 12pm. In high school I would sleep at 4am, wake up at 8:30 for school, then sleep the second half at 4pm when i got home. Earlier this year I was sleeping at 3 in the afternoon until 11pm at night, then I would stay up all night and go to work. Today I fell asleep at 7pm or so and woke up at 2am, just been watching a show and listening to music since then while waiting to get ready for work. Often times if I try and maintain a specific time of sleeping I will roll around for hours awake, or alternatively I will only sleep for a few hours and then fall back asleep later. The longest ive been able to manage a consistent sleep time was in 11th grade, for about 6 months I slept at 11pm but gradually my body started wanting to push later and later. I tend to only get a full 8 hours of sleep one or two nights per week as well, sometimes I’ll drink alcohol to help sleep longer but only on a friday or saturday.
