My sleep cycle is getting more and more screwed up. I am currently falling asleep anywhere from 4 - 7 AM and waking up around 3 - 5 PM. I have tried everything....melatonin, tryptophan, sleeping meds, proper sleep hygiene (same time to bed, same time up, dark room, quiet, white noise, no caffeine, no alcohol, cool temps, getting up if not sleeping, etc), warm milk, warm baths, exercise early enough, etc, etc....I've also tried light therapy, stimulants, etc....nothing works.....anyone else deal with this? Any suggestions that I have not tried? I literally cannot function if I get up in the morning and I get really sick (nausea, vomiting, etc). This evil illness is bad enough w/o being on a completely different schedule than the rest of the world.
