Dazzy,
Miralax and Movicol are the very same thing; just have different names due to countries. I know I am dependent on Movicol, but it sure beats having an AF and the pain and anguish that goes along with it. All my docs have assured me that it is not absorbed into the body, but I do not like putting a chemical into my myself. Considering the alternative, I'll keep taking Movicol. Docs also give/suggest Movicol for babies and toddlers. I personally know of 2 children that are now taking it.
