My in-laws used to get kidney stones all the time it seemed - but also refused to drink water - only sweet tea, soda, and Gatorade - and it never seemed pleasant. Sorry
I would be curious what your macros were while doing strict IP. For the 9 months I was on, I was 50 / 30 / 20 (P, F, C) almost daily.
Again, sorry for the issues - has your pDoc suggested a program better suited to your needs? Or have you looked at the IP Alternative Phase 1 that allows a limited amount of carbs/fruit - designed for T1 diabetics so they don't go into ketosis? The file is attached if you're interested.
