one thing is that after gallbladder removal, bile is constantly flowing into the small intestine, which can’t cope with all its amount, so it can’t be re-absorbed in the small intestine completely, as normally, but reaches the colon, irritatres it and triggers “bile site diarrhea” (read about treatment options):

Next, all medications you’re taking maybe derranged your normal intestinal bacteria, which task is to prevent overgrowth of harmful bacteria, like Clostridium difficile, that, again, can cause diarhea with “barnyard smell”.

Vodka, when your intestine is irritated by bile and possible infection(you also say – cold), can add a lot to irritation. Telling you openly – your doctor has reason not to believe you (explaining with vodka and anxiety), and exactly this can be dangerous for you.

Suggestion:
- drop vodka nad fatty foods
- visit a doctor and ask for “stool test for Clostridium difficile toxin” and mention him posibility of “bile salts diarrhea”. Take your time and write down your complete medical history in a factual, chronological way – with the help of the link in my previous post. All details , as you disclosed them here are important for diagnoss.

When you had colonoscopy?

would you say your problems changed, worsened or lessened after galbladder surgery (stool color, loose stools, pain location…) or not really?

Is your stool more on the bright yellow or pale/colorless side? Do you ever have white, sticky, floating stool?

More symptoms? Check medical history questionnaire

What is your diet in general?

revealing seemengly minor details, like it helps when you stretch, can help finding a cause a lot. Check medical history questionnaire and write down anything related or not:

Muscular abdominal pain is common after exercise or physical work, but it goes away – you would kinda know this. Pain does not likely appear from just being un-trained.

Think carefully, have you taken vitamin B supps or iron (green stool/urine). If not, then blood tests for bilirubin and liver enzymes, stool and urine tests for infections can give a lot of info. Bacterial or parasitic infections can cause left lower abd. pain (specifically ask for giardia and Cl. difficile). If all this is negative, colonoscopy is an option.

Adhesions, when all tests are negative, should be considered.
