Caffeine, carbonation in soft drinks, artificial sweetners... all on the "bad" list.
Decaffeinated coffee might be OK... I knoow regular coffee really messed me up in the early stages and can still cause minor stress incontinance in me today if I am doing work using a ladder or getting up/down off ground. Today, alcohol late in the evening if I am also tired also can cause me problems.
During the first few months post-op, I was very sensitive to anything on the list...
Good luck... and it will get better...
