That happened to me a few weeks ago with Celexa, and I'm not going to lie, I really didn't feel great. HOWEVER, it didn't make me v*, and it won't make you v* either. If you get side effects (which you won't necessarily get), you'll probably just feel kind of crappy overnight. My symptoms didn't last longer than a day or so. Try and stay calm, you will be ok and in the long run it is a good thing to be on the zoloft! Don't beat yourself up for starting on a higher dose, it was a mistake and you will be fine.
