Beautifully, I was on zoloft for 2 days and didn't stop shaking the entire time. It was so bad that my body hurt from moving so much. I called my dr and was taken off of it immediately. I was only taking half the prescribed dose with my drs ok. My SI got incredibly worse and I was admitted to the hospital the night I stopped the meds. I was put on cymbalta while in the hospital and had good results with it. I have the tendency to build up resistance against meds and have done that now with the cymbalta. I have been on it for 2 years.
If you feel like you are getting worse, don't wait to see your dr, call them now and tell them what is going on. Hope you get some answers and start to feel better soon.
