Yes I certainly do. During that episode of bowel inflammation which would have healed by itself instead of being murdered by augmentin, !!!!! , I was told to try a probiotic so I bought Florastor. It's outrageously expensive, the Pope makes it at night so that's probably the reason. Forget it. Of course, my bowels were already missing its colony of bacteria so whatever the Florastor introduced cause GAS PAIN that sent me BACK to the ER and there was no infection or anyting, and DIARRHEA for DAYS. Recently, because my gastroenterologist doesn't seem to know much about anything, I tried acipophlus. They make these tiny little pearls very easy to swallow and I started taking one three days a week, went to four days a week, then every day a week. Mind you, this is the most benign probiotic on the planet. Well, it gave me copious amounts of BM and THEN it turned the BM into sausage shapes and darker brown and THEN it pretty much gave me such bad dry mouth (I looked it up, it's a side effect) in the middle of the night I had to get up and get a hard candy. SO I stopped it BUT it takes a couple of weeks to really get back to normal. My BM finally did get back to normal yesterday, a full week, but it did something to my sense of balance too because now in the morning suddenly I'm getting weird feeling of dizziness, that's a rare side effect. DON'T DO IT. And yes, I'm in the age category where you just drop dead and I wish I could.
