Had it for years. Every 1- 1/2 weeks I'd get it, no warnings, very embarrassing. My nurse PR said, some kind of a bug, nothing I can do. My wife was plagued with it too off and on, but not as bad as me. I had forgotten that I used to take raw unfiltered vinegar for it a long time ago, 1-2 tbsp w water every morning. I bought a btl, stopped it right now. Got tired of the hassle and nasty taste, likely why I quit it before. I bought some vinegar capsules from walmart, just 1 in the morning does the same thing. Works great. CHARLIE.
