Why am I still getting diarrhea every morning?

I have the worst colon so I feel for you. I have tried drinking fiber. I've tried being sure I have all my water in. Nothing seems to work. I bought some probiotics from cvs and they didn't do a darn thing. I bought some online and they worked. I looked into it and found out that the ones I bought have a special coating that other probiotics dont have. The other ones burn up in your stomach and dont make it to your colon where they belong.Here is where I bought them....oh btw...I took the probiotics and prebiotics, but I guess if you took just the probiotics you could find out if they work on their own. Then if they don't add the prebiotics. the probiotics are a tiny little pearl of a pill. The prebiotics are a powder you just mix in with your juice or whatever. It had kind of a fruity flavor.
