No I drink very rarely, not enough to worry about. Speaking about gallstones, I actually think I passed a few today on accident after taking some cayenne pepper. There were some green pea sized balls in there (only 2 or 3 i believe). I do eat a lot of peanut butter which is high in fat and could cause problems I guess. Besides that my diet is healthy and normal.
I am on probiotics, but have never taken digestive enzymes although I have looked into them. Interesting, so you think it could be a liver problem to go with a parasite possibly?
