Started taking genetic Wellbutrin three weeks ago immediate release. Found out not only wasn't I taking it right but the side effects were horrible. I did feel lots energy didn't eat much but felt the medication hit all at once to fast. So I asked my doctor to switch to the XL which started last week. Same does both types of meds. Since taking the XL feel nothing 150 mg no energy anymore not one day. Side effects are better. My mood isn't. So wondering if the SR might be better fit. But I worry about the sending dose as so far don't have any issues with sleep. Getting very frustrated
