I have post traumatic stress disorder (4 car accidents in a year, 3 totaled cars, none my fault). I took Zoloft.. its been the only medicine that nearly stopped my panic/anxiety. If you can live with the side effects, the drug I would reccomend. I quit taking it because of the numerous side effects. I take wellbutrin now and it helps some of the time.
Until reading this post, I hadnt paid attention or realized that I have had far fewer panic attacks while driving, since low-carbing. What an amazing thing!!
