I used to take 1200mg of this a day as that was the amount recommended in a study. I found myself more talkative, more organized and more motivated to do things. I now only take one capsule a day and although the effects aren't quite as strong, they are noticeable. I go into autopilot at work and don't seem to forget things as easily.
