I’m so sorry you are going thru this too. I also have IBS-D . Recently I’ve been taking Metamucil crackers. It seems to be helping me. I’m also on a anti spasmodic drug to help with the internal tremors form the last 2 weeks. I’m still having the tremors all day and night. I had my gallbladder remove 20 yrs ago. Reading your article sounds like what i go thru.
