"i have bipolar disorder but mainly suffer with depressive episodes which can last up to 7 months . i had high hopes for this drug as i am drug resistant now and have tried every antidepressant and  mood  stabiliser. i expected it to  be a stimulant! i&#039;ve only been on it 2 weeks and my shrink says it needs 6 weeks to get into my system but all my research points to a stimulant working within hours . i&#039;m on 10mg 3 x a day and all it does is make me sleep! not very stimulating! this dose seems to work for most people, maybe i need a bigger dose but overall so far i feel worse because i hardly have the energy to get out of bed and i feel more stimulated by caffeine, side effects for me were intense headaches and nausea, lack of appetite."
