"i&#039;ve been on it for about a week, just about to up it to 30 mg.  i have had no dizziness or nausea.  i can say for me, it has an immediate effect after taking it. i feel just a tad loopy and very relaxed for about an hour after.  not sleepy or anything, just relaxed.  it has definitely suppressed my appetite.  it seems to be working already, i&#039;m not grinding my teeth all day, so my jaw no longer hurts and i&#039;m able to focus a bit better.  i like it way better than clonazapam or any benzo i&#039;ve been given.  i do not get panic attacks and i&#039;m also on bupropion."
