just keep looking, as far as I know it is fairly new. I do know that it is not like the others. It differs in the fact that it is a non stimulant.
In my opinion every one else on here has a first hand experience with it and the post on here go back pages. Read. read, read and then ask alot of questions. There is a right combo out there for everyone. It may be hard to find and unfortuneatly it ia all trial & error.
Good luck in your search
