Well, I did not hear from doctor and had to go out yesterday so I took one Imodium and then one 4 hours later. Still had to find a bathroom after lunch quickly but only once and not bad at all.
I have taken Imodium with my primary care doctor's ok in small amounts for years before DX with UC. It has never made me constipated - helped a great deal as someone said when "necessary" such as plane trips, etc.
I really would not mind trying the enemas BUT I am too obsese (and embarrassed to say) I cannot administer enemas. Maybe if Canasa is still not doing much in another week I will ask doc about the pills.
Thanks for all your advice - I can see doctors definitely have differeing opinions and yes, I have been concerned after reading about megacolon.
