Are you still drinking any type of energy drinks, even if it's caffeine? All that ish can mess with your head, and teeth for that matter. I use to drink Rockstars on the regular, but started losin' it on people, clients, my dog, etc, so I had to stop. Then I took up Monsters, which isn't as bad, but still gave me anxiety and jacked up my teeth. Then I migrated to Coffee, a somewhat lesser evil, but it causes delirum
http://en.wikipedia.org/wiki/Delirium so I cut back big time, then some more, and finally just drink a small Hot Chocolate every morning.
By the way, what Greg said about the effects of Sativa and Indica are on point. A hybrid, leaning towards the Indica side are ideal if you have anxiety. Alls you need is one hit though. I just to go full blast, but over the years have been weaning off substantially.
Peace.
