Thank for asking to HCM
I really appreciate your concern from the history given here I could say that you made a serious mistake by taking the Imodium
this is ban drug, because this cause a serious Para lactic ileus
, which immediately stop the diarrhea
and some time distend the abdomen, this is must have happened with you, now just do nothing every thing would be alright, hope this information helps you, have nice day.
