I suffer from major depressive order, I was given to take bupropion hcl 300mg per day. I found very little results, so made the decision to double my dose 600mg per day. For the last 3 days I've taken 600 mg; I have felt a world difference in my state of mind and mood. My Q is there any danger in taking 600 two tablets per day. FYI I am a 62 year black man at 355 lbs. My thinking is that my size/gwt may require a larger dose. Is there any danger.
