I’ve taken B12, Magnesium and Zinc together for stress now and again (before a dental visit, etc). I stumbled upon the combination years ago when experimenting with vitamins and noticed a dramatic improvement in my thinking and feeling. Earlier today I was feeling miserable. hot and cold sweat, couldn’t stand fabric on my skin, taking it off did not help. Laying skill was not helping, nothing at all. Not sure how to describe emotions beyond miserable although a few times I asked myself “is this sadness? I don’t know”. Thought it had to do with the yucky humid weather maybe? Wasn’t sure. But somewhere I remembered B12 and Magnesium. I skipped the zinc this time as an experiment and did b12 and magnesium. About 20 minutes later, it was like a light switch clicked on and I felt functional again. Oddly dramatic. Any ideas?
