I usually get biscodyl supp. from my drugstore and a lot of times have butt snot afterwards. Well i was in Fla. and got some glycerin supp. cause that's all they had at CVS. I used a half and didn't have any after effects with the glycerin. Is there a big difference? If so i'll start using the glycerin.Thanks for any help.

I'm c-6-7 18 years post. I just use half a supp. and sit on the toilet chair til i go.
