My advice would be to switch to evenings if your hospital offers it. After I was diagnosed Bipolar I read a book by Kay Jamison "Touched by Fire." Most people in a manic phase typically fall asleep at around 3 or 4am. This is true for me. Anyway, I sleep great now that I made the switch (I sleep from about 4 to 12) I take very little in terms of meds and feel great (have for a few years now). Seriously, if you want your life back (and your sanity) try evenings. I tried the 20 mins/day in the sun thing as well as a set sleeping schedule. They don't work. I tried EVERYTHING. Please consider it. You will feel soo much better. K.
