I have been on 37.5 Paxil for 15 years. Recently stopped being effective. Anxiety and OCD back with a vengeance. Tried upping to 62.5 with minimal results. Dr. now trying .5 mg of Lexapro. On that now 2 weeks, dont see a difference yet. When I start reducing the Paxil, Im so scared Im going to get worse. Anyone have success with this switch?
