I've been on this for about 15 months to help control the diarrhea. I've been taking it at night(4g) after I have finished having anything to eat and it really works. However, apparently I haven't cleaned my mouth (brushed my teeth) well enough before I went to bed.
My teeth were cleaned only 9 montha ago, and I have since developed a massive dental project consisting of replacing a 5 tooth bridge, and two new crowns and a root canal because of the enamel damage. Overall, it looks like I will be spending around $9k!
