I had Giardia a few years back. Probably got it from my grandchildren who picked it up in their nursery school. I went around with it for about a month while gulping a lot of Imodium which did not put a dent in it. I was finally referred to a GI specialist who recognized it and diagnosed it with a lab test. The cure was actually easy and effective, three horse pills and it was all gone. I don't recall the name of the medication but do recall that it had come from Europe and was just recently approved in the U.S.
I don't recommend it for weight loss, but it is effective. I lost 20 lbs during the ordeal.
