Whenever I thought I was getting some prolactin rebound I took B6...I really wanted it more as a placebo just so I wouldn't freak out, I'm not too convinced on it's effectiveness. I often wonder if the people who are convinced it works are referring to injectable B6 or the oral form that most everyone buys and takes (ease of access of course). Caber is always a better option, but incurs many more sides. I'd go with caber for the sake of keeping my mind at ease...I view B6 as a risk. Perhaps start on B6 but have caber on hand.
