I, like others, go a week or longer without a BM and when I do have one the stool is very hard and I strain excessively. Miralax does help me but it makes my body feel extremely cold. When I had my last colonoscopy, after drinking the gallon prep, I was so cold I was shaking uncontrollably and ended up in the ER. I am gluten free, fructose free, and dairy free--anyone else with these issues? Also, curious whether there is any type of sugar in Miralax.
