Hi,
Having CKD I don't touch man made or adulterated food stuffs at all. They all have a bad habit of adding in artificial this or that which notoriously comes back to bite years later when it is discovered to be bad for us. I try to stick with natural and fresh with minimal red meat, no salt or sugar and it is boring but required to maintain kidney function. Currently trialing metformin for the third time and it hasn't started well. Day one pure aggression yet again, immediately stopped it to give some thought to what I should try next. So as it can't be cut as this changes the delivery time frame I'm opting to take 500mg every three days to see if I can break the side effects I experience. If this dosen't work it's goodbye to medication for sure. Interesting my doctor is starting to agree that my thoughts of the body being used to higher amounts of blood sugar for so long it complains bitterly when it is artificialy dropped. I get the same reaction with blood pressure medication and only take enough to trim the really high BP to stop the 24/7 migraine. Keeps me around 150/100, comfortably.
Cheers
