I am taking 100 mg of Zoloft every night . I feel like I am having withdrawls from it. I have been in the hospital before for the withdrawls. This also has happened when I was on Paxil. That is when they switched me to Zoloft. I want to quit taking it, but I am so scared of the w/d. My brain gets all fuzzy and tingly, and it feels like I can feel all the blood run through every one of my veins!! Am I supposed to be feeling like this?? I have been on ssri's for 5 years now!! As a side note, I have also gained 50+ lbs too!! Thanks everyone for your support and help!!
