I do regret when I sleep half the day away. I take meds now that make me tired enough to go to bed early so I don't stay up all night like I used to. have you thought about taking melatonin to reset your sleep cycle? I also had to cut out caffeine. discovered I was highly sensitive to it and that is what was keeping me up all night. even the b vitamins in vitamin water and the ginsing will keep my mind buzzing so I cant sleep. so watch what you drink. do things that aren't over stimulating in the evening. I find going to bed at the same time every night, even if I don't think I am tired, I still go to sleep. take care.
