I believe i am having really bad side effects to this crap! I am still going to the Dr. to get tested for other issues. But so far my symptoms are the runs, bad cramping, having the need "to go" but not really having to "go". Terrible heartburn at times. Most of this happens an hour or two after a meal. I know there is another thread addressing this issue, but if anyone has had similar symptoms to this stuff in the past... can you give me an idea of how long it can last? I am so uncomfortable and terrified at this point.
