I've had both Nem and Exodus, and they arent the same.
Nem is great for keeping you up (can be a little too good). You do get a major loss of appitite though, and have to force yourself to eat the next day (or 2 days even?). I've had that quite a few times, although not recently.
Exodus, for me personally was fairly good the first time I had it (2 caps a time only), but the other two times didnt give me much of an affect, until the end of the night and the next day when I had a major comedown (which I dont actually get when pilling). I just felt like a peice of crap and could have done with lots of cuddles, but didnt have that which made it worse!!
I was told by the guy at the hemp store that Nem had been taken off the market, but would be replaced by an improved version to be called Frenzy.
Anyway, out of interest, I'll try both these products again some time in the nearish future, especially since I've all but given up pills (sob).
