Hi Max.
First, I hope you're feeling better.
Second, it sounds like you either took too much or too little enzymes for what you ate.
If you're just starting to take enzymes, you may have to kinda experiment with the amount you have to take with each meal.
What kind of enzymes are you taking?
I take Pancreaze MT-16 & MT-10. I take one MT-16 with a bowl of cereal. I usually take four with my big meal of the day, supper, or lunch, whichever is the biggest meal I eat.
When I eat a sandwich, I'll take one of the MT-16's & one of the MT-10's.
I've got my dosing pretty well perfected.
Of course, there are times I still screw up. When I do, I pay dearly.
Like you, backache, bellyache & the whole bit.
Usually I can clear things out by doing a couple of doses of Miralax.
When having to 'clean out' I'll take one dose of Miralax every 5-7 hrs. until it all goes away. Then, I'm good until the next time I screw up!
Recently, my CF doc told me to do a dose of Miralax daily, for maintenance so to speak. It has been working great!
Maybe you should ask your doc if this might be right for you.
Best of luck to you, I hope I've been of some help.
