My new Dr suggested this possibility. There is a test, but said just add B6 & zinc [not together at same time] & see what happens. Sure nuff, after a few weeks I started remembering my dreams, plus started to sleep better during the night.
He also had me take some berberine & grape seed extract for BP called "CM Core". Ran out & was wondering why BP was on the rise. Was trying many things until I remembered this stuff. Now starting to recede... finally. Do some research on this herb, as well. Good for insulin resistance, too.
Not sure why berberine has not been mentioned before on this forum. Swanson's carries berberine.
