Yep. Klonopin definitely. Also the tizandine (muscle relaxer) I sometimes take for fibro; it's a prn med, so I don't take it daily, just when I have a flare.

But I think the more medications I take that can cause drowsiness, the worse the slurred speech gets. So if I have a bad panic attack and take Klonopin, propranolol, and hydroxyzine, and that is not helping, I can also take 1-2 25 mg Seroquel tablets. All that, and I slur constantly.

I think Wellbutrin worsened my speech issues, but I can't be sure. I've only been off it a few days now (had bad forgetfulness the pdoc thinks is either Wellbutrin or Clonidine).
