I can tell you that my experience with armod has been much better suited to me and that's what I use instead. I usually get weird looks when I say the other thing only made me sleepy.
I would recommend armodafinil over modafinil. Armodafinil has less side effects, and also is a newer gen of medicine than the original Modafinil formulation.
True. I couldn't for the life of me figure out why it was doing the opposite of what it's supposed to do. I was prescribed it so I was just told that it may not work in some people and then put on armod.
