I just started Wellbutrin 5days ago, to help me concentrate in college. On the 3rd day, I noticed a couple of things: I got a moderate headache, I felt my heart pounding from my chest & racing (palpitations), I felt I was cut off from the world "like I was a puppet and someone just cut my strings" but the one thing that made me stop this med after day 4, my eyelids got swollen and it looked like I got socked in both eyes, with no bruising. I took Benadryl, Tylenol, Aleve, and none helped much, however I did get some relief with Motrin. I've have been off Wellbutrin for 2 days now, and all of my side effects have been decreased into half; I'm just waiting for my body to get rid of this stuff out of my system. I have yet to contact my doctor, due to the weekend/holiday, however he did warn me that the first 2 weeks it will be tough, and the side effects would go away in the longterm use, but I couldn't hang. I went work, and all the nurses I work with noticed I was "out of it", and my eyes were swollen, I had to go home ill, because I felt like I was going to pass out and my eyes were going to pop out. I hope this was somewhat informative and good luck to anyone that is on this med.
