I've used it for anxiety, and it works really well. But, getting back in the gym after a long layoff did much more for anxiety than those pills ever did. Guys have a lot of energy, burn that shit off in the gym. The build up of (can't remember the exact term, lol) stress hormones needs to be taken care of.
I will use it occasionally before a big broadcast/tv appearance, just because you can't appear nervous in my line of work, but i use it twice a year, at most.
