Hi Brachial6

You have my sympathy on the diarrhea issue. I had a chronic case after an appendectomy and the accompanying antibiotics. Due to an autoimmune condition I have to take steps to avoid getting chronic diarrhea and I can back up Deja Vu's suggestion re probiotics. That's my first line of defence. I take either LactoBif by California Gold Nutrition or PB8 by Nutrition Now - both available from iherb. The PB8 is much stronger (14 billion CFU) - it's so effective I suspect it tends to cause the opposite ie: constipation - if taken daily when the digestive tract is functioning healthily - so I use it less frequently but it's great for stopping an onset and good against candida. The LactoBif (5 billion CFU) is more tolerable for every day gut maintenance.

I hope this may be helpful although the cause of my diarrhea is different to yours - all the best for finding a workable solution.
