lahgarden (hey,it's clever of you to not capitalize your name-easier to type!!)
Anyway, I'm wondering about the dosage of B12 you are getting. My little pink pills are 1 MG.
Maybe someone can explain what all the dosage letters mean?
Also, have you considered dropping the SAMe stuff & see if it helps your tummy?
Here's some more whacky brain incidents I've had: went an entire year thinking (insisting actually), that I was a year older than I was.
Would get in shower & wonder how to turn it on,also would forget to shampoo hair & have to get back in.
Gave my maiden name over the phone (which I hadn't used in over 34 years)
Used a combination of my parent's phone number & my own.
Wrote my own address down rather than the person I was mailing a letter to.
Did I think I had early dementia?? You bet ya! Since I'd been told possible Parkinson's I suppose I just figured I was odd enough to have BOTH mental & physical problems from it (my research had shown you either present with one or the other,seldom both).
Hope some of my brain quirks gave someone a chuckle

The point is that B vits have saved my life!
Take care & don't despair! Buttons
