I had my gallbladder removed in 2006. In 2011 I started having diarrhea, There’s nothing physically wrong with my digestive system. My doctor said that I have bile salt diarrhea which can develop after some people have had their gallbladder removed. Some people never have that problem. I need to take a sequestrian medicine to help with bile salt absorption. I take colestipol, it is in pill form, twice daily, which is easier for me to take them the powder cholestyramine. As far as sleep, I am still working on that. Good luck to you and I hope you continue to heal and do well. Take it easy as you just had the surgery and try to avoid any scar tissue buildup.
