Experienced the side effect of llightheadedness, dizzy, fuzz like not all there when out. Xanax is the best drug for me for panic and anxiety attacks but doctors don't like to give it, it can be habit forming. 1/4 of a mg twice a day works for me, so why should I take Paxil or Prozac, Prozac had the same side effect as Paxillll, those mind altering drugs are drugs are just what the are called. Mind altering, lost sex drive, gained weight. Having problem with rapid pulse, have been off for 6 months now, will never go back. I have friends that use Prozac or Paxil and swear by them. These drugs are just what they are called drugs.
