I've tried for a long time to get my sleep schedule straightened out. I've used iOS apps, taken LOTS of NyQuil, cut out caffeine, read as many tips and tricks as possible and still can't get on a set schedule.
Case in point, last night I went to bed right at midnight with the plan of getting up around 7:30. A good night's sleep and up in plenty of time to have a full day to get done any and every thing I needed to do. Instead I tossed and turned till almost 4 AM and still woke up before 8 only exhausted and no desire to do a thing - except take a lengthy nap that will no doubt screw up my sleep tonight. Causing me to take another nap when I get home from work tomorrow and start the whole process over again.
My body is now set to wake up before 8 AM regardless of how much (or little) sleep I got the night before. Unfortunately when I try to go to bed early I just lay there and fret over not sleeping. If I stay up till 4 I'd love to sleep until noon. I'd take that over waking up early, feeling miserable and ruining the afternoon sleeping.
It's not stress or depression. Sure, occasionally I have a lot on my mind. Most of the time though my mind is completely blank except for the nagging fear of never falling asleep.
I'm tired of being tired. If I could just get one good night of sleep at the right time I could get my body back on track. I'm just at a loss on how to do that.
