bipolar disorde
"I wish I could echo all the positive stories mentioned in this string of comments but...I have had some inconvenient side effects including: double vision, fatigue (even with regular exercise, somewhat healthy diet, and a healthy amount of sleep each night) and major hostility, particularly with those close to me.  Maybe my dosage isn't right but I am not sure I want to stick with it.  I take it in addition to a fairly low dose of Lamictal."
