Started mine in September 2009, three months before I was diagnosed with a severe case of clinical depression. Coincidence, not sure. I'm a hisser for the record and am usually "clean" when I wake up and then the hissing builds through the day. Looking for a hisser just like me to compare notes. I got my doc to prescribe Campral (Acamprosate) but I didn't see any results. The loudness has crept up since Xmas as has the tight jaw. Tough to break the cycle.
