I am to have a cck hida scan this Wed. and I have been in one horrible flare up for the last week, 10-12 loose movements a day. Imodium is not even touching it. I must up the dose if I can even go through that test. You have to lie there for 2 hours or more!! There is no way I can do that. They will not let you up to go once they inject the dye. HOw many Imdium can you take without over dosing yoursef. I must take it tomorrow because you cannot eatr, drink, or take meds. 6 hours before the test. Please help I am so nervous , I am thinking of canceling the test.
