Wow Donna! Coke for the peg tube, huh? I never heard that one before!! Amazing how different docs have different solutions for the same things. We always only flushed mom's peg with water......the poor thing always thought she would eventually float away!! Sooo much water, but, boy does it help!!
Also, Midwest Gal....always check with the doc about crushing pills, but in our experience, the only medicine we couldn't crush for my mom was Oxycontin and believe it or not, her Iron .....anything that's time released is not crushable. Once she was to the point of not swallowing anything, those meds were simply out of question. Thankfully, these days, there are many meds available in liquid form, and many others crushable.
Good luck!!
