Hope you feel better, Tibs. Sorry to hear that.
Watch out for too much IB's, they're hard on the kidneys.
Tylenol is metabolized by the liver, IB by the kidneys. Can be taken together IF you know you can do that. But both are hard on each organ for long-term use or at higher dosages, and even in the short term if you have muscle damage, since "muscle stuff" in the blood can cause kidney damage, so drink plenty of fluids and get some electrolytes too.
Don't ask me how I know, and this is a generalization written to keep you safe, not "giving medical advice". So it's an FYI that you will have to customize to you.
IIRC you don't take statins, right?
