I have been using tincture of Opium and it is a wonder drug for me.  Imodium did not agree with me.  Try the tincture it works for many.  I had no side effects 

Thank you...Im hoping my doctor agrees.

I’m also on opium tincture (script from dr. Shen ) yes it works. I take a very small amount ( 1/3 of the smallest dosing syringe that you get from drugstore when you get any liquid) I take it twice a day—stops cramping within 30 minutes. I take it with water—the taste leaves something  to be desired!

drugstore usually has to order it.

Yes - one does not need much - like 1/2 of an ML - I take a fraction of the normal dose.  It tastes absolutely horrible.  But it’s no big deal. 

Thank you!   For some reason she is hesitant on ordering that.  She's switched me to morphine...

In my opinion, the opiate restrictions have gotten out of hand. I currently take tincture of opium and it works wonders. Gentle. Immodium constipated me. My new gastro will not prescribe opium and my family doc, who has been doing it after my old gastro retired, is now retiring. I have a consult with the new gastro Monday and will ask about alternatives. I really like her, but if we cannot find something that agrees with my body, I will need to find someone who will. 

I hope morphine works for you. I have never taken it so cannot give advice there.
