Welcome to HealingWell!
I am so sorry to read of all your struggles with your guts. Unfortunately, it isn't that uncommon for people without a gallbladder to struggle with bile D. You came to a great place and, hopefully, we can give you some great tips and be here for support.
First and foremost, have you looked for another GI doc? I went through 2 before I found a 3rd to stick with. It's hard finding a good doc that takes the time to listen and not shove you out the door after 4 minutes.
What is your current doc's action plan for helping you control you D? I really hope s/he hasn't cast that aside as "normal." If you look around this site you'll find the most common suggestion for D associated with no gallbladder is a combination of Welchol and calcium. Welchol is actually a cholesterol med thats side effect is binding bile and helping prevent D. Calcium also works by sucking up the extra water in the gut. I would definitely talk to your doc about
trying both these options. Calcium you can buy yourself OTC, but Welchol is prescript
As for you anti-spasmodic... You should ask your doc for another. There are so many on the market that you should be trying a new 1 each time you get 1 that doesn't work.
Remember, no one is going to fight for you but yourself. Be pushy. Ask questions. Demand to be heard.
I hope others come along with more tips for you.
Hang in there and NEVER give up hope.
