I read that high doses of this can cause hemorages...so be careful.

Years ago I took "brain pills" (contains d & L phen) while in college, and I retained everything I heard, didnt study at all and I had an a-b average. The strangest thing about it was it gave me "out of body" like dream experiences. No drugs involved.

I believe it is used (or was used) in dexetrim as an appetite suppressant and it does work well, but it makes you feel mean in these doses.
