Currently have been on wellbutrin itself for about almost a month. Previously I was on venlafaxine and wellbutrin, then got taken off the venlafaxine (wasn't for me). This is my first time being on the drug itself and I've had side effects such as, nausea, headache and vommiting. This morning I woke up feel worse than normal and vomited a lot more. Wondering if this is worse because I took a couple hits last night or if it's just the med?
