I have been off WelChol for about 3 weeks now thanks to this web site. After about a year on the drug I had enough pain in my shoulders that it prevented me from sleeping. I stopped the drug after reading the comments here and the pain has diminished each day. In addition headaches, night sweats, leg pain and fatigue have been greatly reduced. For me, WelChol is poison and I am very grateful that each of you shared your experience since the drug company doesn’t provide this information.
