You must be mistaken. I've never recommended nolva for PCT, only for existing gyno. I think it's a horrible drug and would avoid it at all cost.
Clomid and nolva are almost identical. I may actually hate Clomid more.
My recommendation for PCT is HMG, UNLEASHED, POST CYCLE, and a small amount of an anti aromatase, followed by BRIDGE.
Too much B6 can cause insomnia. Needto and I have an anti-prolactin supplement coming out, but it's gotten held up. In the meantime you can try some cabasser. It isn't great, but it's the only thing yet available to treat excess prolactin.
