Last month, my Dr. recommended that I switch from Paxil to Serzone because of weight gain. I gradually weaned off the Paxil for about a month, went one week without anything and now have been on the Serzone for 5 days. I feel soooo depressed, though. Worse than I've felt in years. How long does it take for Serzone to become effective? Does the dizziness ever wear off? I feel like I'm going to jump off a bridge or something. Has anyone else out there tried any other med which helps with anxiety & depression and doesn't make you gain weight?
