I recently started having major anxiety and the dr started me on Zoloft which made my anxiety go through the roof. I literally felt like I could not function. I took that for 6 weeks before I said I'm done. I didn't take anything except for an occasional Xanax, maybe once every 2-3 weeks. Now I started taking Paxil 4 days ago 10mg and I feel like my anxiety has doubled. How long does this last? Is this normal?
