Okay, thanks! They started me out on 150mg XR, which is the lowest available dose where I am. It's either that or 300mg XR. Apparently I cannot get the immediate release version here. So far it's made me very dizzy and my blood pressure has gone up 20 points. I've also had insomnia and now I'm starting to get really irritable, although I'm not sure if that's due to the bupropion or the lack of sleep. I'll give it a few more days but I'm not sure this is a keeper for me.
