Bupropion
"In my experience I have most often taken the Bupropion XL tablet that is oblong; and that is one that I have absolutely little to none side effects that I actually notice. However, when I got my refill from the pharmacy a few days ago, they filled half of the bupropion prescription bottle up with the normal oblong ones (on the bottom) and the strange round ones at the top. I had to actually research what the inscription on the pill meant to make sure that there hadn't been some sort of mistake. Anyway, I immediately noticed after taking this round type pill that I feel a ''buzzy'' sensation in my head that is very hard to explain. It is very disconcerting."
