Welcome to the club!
Feel free to ask any questions... There is bound to be someone here who can help / give ideas.
Is Questran like Welchol? There are a few member here who take Welchol to help control bile. Hopefully they'll be around shortly....
I took Questran, but I think my bowel issues are somewhat different, and it didn't work for me. HOWEVER...a lot of people have had success with it. Keriamon will surely be around and rave about the wonders of Welchol, which is similar - she loves the stuff!
Acidophilus is a type of "good" bacteria that is naturally found in your intestines and helps regulate the digestive system. Taking it is a good idea. Go to your local supermarket or health food store and ask a crunchy hippy granola person where you can find the probiotics, preferably refrigerated. Start 'em slowly because too much at once in the beginning might make you gassy. They are very good for your digestive system!
