I tried a few times in fits and starts….hung in but each time RX renewal came due, I didn’t want to spend another $50 to continue. It’s cheap enough in low dosage, but who knows what is the right dosage for what problems and every patient being different….could be anything. Years earlier, I spoke to a pharmacist who told me that it would cost $50 a month and I’d have to use it for 2 years before I would know if it would help!!!
