Hi, I'm new here, but have been struggling with IBS and severe reflux issues for quite a while.Seeing a motility specialist now for reflux-related pain, and he put me on a couple of drugs that caused extreme constipation (not my usual problem). After a week with very small and few bowel movements, an x-ray revealed tons of poop clogged in my stomach.After Millk of Magnesia didn't help, doc prescribed the following to get rid of it all and start from scratch with fiber (he doesn't want to stop the constipating meds, Nexium and Ranitodine):15 Senokot tablets first day15 Senokot tablets second dayOne Capful of Miralax third and following daysSince I know the irritant effects of a stimulative laxative like Senokol, and my own propensity for very bad cramping, I was alarmed and called my GP. She also worried about the side effects, and suggested I start off with something much less irritating, like large doses of Miralax. Last night I took scoopfuls. Today I took one scoop, and will take two more (as pharamacist said). I'm pooping a little bit more, but no big elimination which is what my doc wants. But I'm conflicted --any advice? I think 15 Senokot would be brutal for me -- and this is one of those "no gain, no pain" drill sargeant type specialists, who tells you to grit your teeth and bear it. But I've passed out from severe cramps before, aeven had to go to the ER, and have no interest in repeating that experience!I'm a woman, 59 years old, otherwise in good health and not currently in any pain.Does anyone have advice, ideas on how to proceed, related experiences to report? I'd be very, very appreciative.
