Hello. I feel your pain! A few years ago, I got some really good indirect advice from a nurse who told my pastor's wife about a product I'd never heard of. It helped her so much she told me about it. I did a couple of days researching it on the web as I've had chronic stomach troubles for thirty years. Amazing! It was a Godsend. After a few weeks, I found it was cheaper and tastier if I cultured it myself. Anyways, whether I culture it or buy it already made, I truly believe it saved my life. When I finally first tried it, I'd had chronic diarrhea so bad for five days and nights that I could barely sit up and was severely dehydrated, as I could neither eat nor drink fluids. After just 2 cups of the stuff an hour apart, the diarrhea stopped and I recovered quickly. Then, just last year, I got sick with vomiting and diarrhea so bad I spent 13 days in the hospital with IV's and stomach pumps and massive amounts of drugs. Turns out I had over a hundred ulcers and erosions causing such inflammation that I was deathly ill. The doctors told me that had I not been drinking the miracle stuff, the ulcers would have caused me to bleed to death. I don't sell it or anything, I just use it and it's been like a miracle for me. It a probiotic that's like yogurt on steroids! It's great for almost any kind of digestive trouble from constipation to diarrhea to cramps and a host of other yucky stuff. I'd suggest if you want to try it, you read up on it. Just google it, that's what I did. It's called 'Kefir' and I've been using it for five or six years now.
Anyway, I truly hope you get better soon. I know how miserable you must be.
I wish you well.
