Star, you have a good point and I'll have the doctor check that while he's checking everything else. I know the cognitive and memory issues can also be made worse by the reduced kidney functions and the anemia it causes too. Reduced function allows toxin levels to increase in the blood stream "muddling" the brain and the anemia can also cause issues although usually on a smaller scale.
This is why I'd like to be checked out by fam doctor really well before starting the process. IF the issues that seem to be getting worse are correctable, then by all means I want them corrected.
