I like it a lot, but not everyone responds to it, and others report headaches. I usually take a slightly higher dose than average, and it really effects the speach center of my brain. Canversation is just more flowing, and vocabulary just works better, if that makes sense. I'd say try it out, it's cheap enough from nutra, I think it's even still on clearance. It's effects seem to wear off if you use it daily, though, so I just use it when i've got a meeting at work or a date and such.
Good luck, hope it works well for you!
