@Mountaindewed I'd bet it is the lamictal and/or the Pristiq and/or the antibiotic. The 3 together may be the real culprit. Some antibiotics are nasty. Augmentin makes me so sick I won't take it. I don't remember going off lamictal but I went off all at once because I had the rash and I was so sick from that I wouldn't have noticed if the withdrawals made my head explode. I don't know about Pristiq but my experience has been most ADs are hard to go off even when I've gone off very slowly because my pdoc knows I tend to have trouble. And having a sinus infection on top of all that, I think it's fairly reasonable that you don't feel well. Hopefully it will start to improve soon.
