I used it last pg, in place of the expensive prescription Diclectin, which is made up of B6 and an anti-nausea drug ( I think). My dh makes fun of me though because one day I accidentally picked up B12 instead of B6, and took it for days without noticing, until one day I read the label. I am very open to suggestion, so I guess I tricked my mind into making it work. I mentioned the other day that I was going to pick up 'either some B6 or B12, doens't matter which one' and he chuckled.
I'll say it worked though!
