Welcome to the forum Joe,
I have no idea if/how those meds affect lucid dreaming but if your getting natural LD's they can't be all bad.

I read that magnesium, B-6, and melatonin make a good combination for dream recall
Personally id just stick with the different techniques around the forum, there's many many different ways to practice and achieve lucidity naturally and without the use of supplements. Im sure someone else who's actually tried these supplements would be of more help though .

Good luck with your lucid endeavours!
