^^ For what it's worth:

Though I've used it many times, rest assured that gallantamine had no major role in my LD'ing development. It's a handy aid, but relatively harmless if used in the manner Zoth said. One warning, though: supplements like gallantamine and huperzine have a tendency to add vividness to your dreams, and make you less interested in becomeing lucid becaus the dream is so cool.

Also for what it's worth, I suggest that you avoid supplements until after you can become lucid on your own... it works better tha way.
