I have been taking hy. for one month now, along with nuxium (for acid reflux) and am doing rather well. I take the time released kind, two times a day. For me, I have to be right on top of it though or I begin getting pain. I really have to stick to a schedual with taking it or I have a couple hours of pain until it gets working again. For now it is a real help, but in the long run I don't feel I can be on it for very long. The dry mouth is bad, except that I drink more water. I think it is effecting my vision and sex drive. But for now it is ebbing the pain, which was terrible a month ago...so I am very happy about that.
