"i am on 600 mg a day 2x300. it is being used to help with depressive episodes of bipolar which i get more than the highs. it seems to of helped stop the very very lows but i still feel low with little energy or motivation. my appetite seems about the same although i have put on weight but that&#039;s down to me not working now. sleepwise i struggle to get to sleep but once i&#039;m asleep i sleep for about 8 hours."
