Have you tried using less Lomotil? You might notice a difference if you reserve it for when it’s most valuable (e.g. before bed and before going out for a while). Have you tried skipping the probiotic for a few days? Some people find that gassy. Have you tried avoiding lactose/dairy? Some people develop lactose intolerance temporarily after a run of loose stools or other digestive disruption. I assume you’re not drinking carbonated beverages.
It is early days for you, 1 month out, and some of this is part of adjustment, but you can probably make it at least a bit better with some tinkering.
