For the past several months I've been going to bed late and waking up at irregular hours. I usually go to bed at 2am, and wake up whenever. Sometimes at 8am to go to work, sometimes 10am to go to school, or 12am if I'm doing neither. Either way I get up feeling extremely tired. I generally get 4-8 hours of sleep, but again that depends on school and work. My sleep schedule got messed up due to school work, job, and procrastination. I'm trying to restart my "sleep cycle". Ideally I'd like to get in bed at 11pm and get up at about 8am. However when I go to bed this early (as opposed to the usual 2am), I simply can't fall asleep. Even if I do manage to fall asleep I wake up extremely fatigued the next morning. The past several months I've just very fatigued ALL THE TIME, and it sucks. I'm just so sluggish, ugh. What are some ways I can get myself back on track?
