I have another question about medications. Because I have depression, OCD, ADD, and PDD I want to know which way is faster for me to get a medical certificate? Get off Prozac, Risperidone, and Adderall, then wait 3 months? Or, immediately switching to Saint John's Wort? If I do switch to St. John's Wort, do I have to let my psychiatrist know that I'm using a different medication? Can St. John's Wort be used without a prescription?
