I went to the Dr. for a change in meds because of side effects on Tramodol, nothing serious just muscle pain. And OMG after only three doses of Zoloft I started having these panic attacks, nevousness and feel awful. I can not even get to sleep at night. I went back to the Tramodol, but the awful feelings are still present. Depression is also back. I will never do that again. How do I get back to where I was? Please help someone.
