Do these side effects go away? Wellbutrin veterans out there?

[JenSMP]

I began taking 150 mg of the generic Wellbutrin several weeks ago. There was a moderate improvement, but I had lots of side effects. So, my doctor prescribed brand name Wellbutrin 150 mg XL. I took that for several days with no benefit at all, but no side effects either.

He upped my dose to 300 mg XL, and I'm experiencing side effects that seem to be getting worse each day, not better. I've been on the higher dose for a week now, and I have SEVERE dry mouth, feel jittery, lack focus, feeling "disconnected" and working memory sucks. I was trying to do some simple math at work, and I had to go over and over it to be sure it was right, and then I had to get someone to check my math for me! It was correct, but it was a strange feeling. It was like I just couldn't get a clear head.

I am having some great benefits with the 300 mg, like more energy, increased motivation (get lots done during the day), no cravings for Cokes or junk food, and enhanced mood.

I just feel weird. Will these s/e go away if I continue with the 300 mg? Have I not given the new dose enough time? Do these symptoms (s/e) indicate that my dose is too high? Also, is taking 2 150mgXL the same as taking 300mg XL? To me, that would make sense that they'd be the same, but maybe not? Can you just stop Wellbutrin if you've been taking it for a month or do you have to taper?
