Yes, Ginger, GFR at 26. The diet you mention is my mantra and has been for 10 years. I'm beginning to think PKD is simply deteriorating my kidneys. Maybe that's just the disease and it progresses regardless. I just took my BP and it stays in this range every time I take it, no matter the time of day. 114/75, 105/73, 111/73...I've also checked it with my nephrologist's machine and it is accurate enough only varies slightly. The two meds I take are lorazepam as needed and lamotrigine which should not affect kidney function, it is processed in the liver. Only Tylenol occasionally. Never NSAIDS. I'll see Neera K Dahl at Mayo this month.
