Janet, it seems you are definitely undermedicated--whether because there's a change between the name brand and the generic or not. Switching back at least for a few days to the name brand should answer the one question. Otherwise it may just be time for a larger dose. You are absolutely right not to introduce anyting else new at the same time. We tried two new things once, and then we didn't know which one to blame when it didn't work out. Carol Horner
