diarrhea after infliximab / remicade iv?

anyone else get such tummy cramps and diarrhea up to a week after the infliximab iv? it really sucks and its so urgent despite me not having any urgency issues as crohns is in remission, but when i get the IV i gotta shit so bad omfg. now they want to change the iv to injections, but those are every 2 weeks, so i'm worried i'm gonna be shitting constantly if i switch from once a 6 weeks iv to once a 2 weeks injection. thoughts?
