Paroxetine
"I took Paxil for 5 years for severe panic attacks and anxiety. I got to the point where I could barely leave the house without anxiety. I was on 20 mg once a day and it worked wonders for me. I felt "normal" for the first time in years. HOWEVER... I gained 50 lbs. I decided to get off and weaned myself very slowly but still had withdrawal symptoms: brain zaps, severe headaches, dizzy, restless, faint, weak and the list goes on. I have been off for 5 months now and still have symptoms. "
