I just started taking it. Dr recommended it for sleep issues. She said it will help calm the 'chatter'. The thoughts you may think as lying down like oh I've got to do this, didn't do that, anxiety stuff. I like it, but I like the quicker relief I get from 5htp. But I've only tried GABA for 3 days. My doc says the 3 keys to weight loss diet, excercise and sleep. Sleep is tough for me. Good luck with it.
