Yeah i WISH i could control when i sleep, but I have lifelong serious problems falling asleep. I've tried all the things people talk about - counting sheep, no screen right before bed, melatonin, meditation, exercise early in the day, etc etc. Some of them help somewhat sometimes, but so far there's no fix. Actually there was one thing that totally fixed it, which was taking zoloft. Taking it at noon everyday completely fixed my lifelong sleeping problems even though it did little to help the depression i had back then. Now that i say it, i think i should start taking it again just because it fixed my sleep so completely.
