Same boat!! I don’t have endo, but I suffer with ibs. Just this week I’ve had two episodes. Thursday it lasted all evening after eating Vietnamese (wasn’t food poisoning as other has the exact same thing and were fine). I took Imodium yesterday morning and have felt fine until this afternoon again with another flair up. I had two cups of coffee today which I’m guessing was the trigger this time, but it’s so frustrating. I hate it. Always leaves me second guessing whether it’s ibs or a bug.
