(((hugs))) Sandy. My mom always drank coffee all her life, type A, onset of dementia probably started 4 years ago while I was out of my home State.
I am an A nonnie and after SWAMI-ing, it specifically said NO coffee whatsoever for me with my "Ex-teach-orrior" makeup. Yet neutral COCOA is the staff of life for me!
No upset tummy and no freaky nerves.
