A mountain dew energy drink sounds a bit off to me anyway. Best off going with the real thing.

I've tried a few different types of energy drinks in the past. Bawls, of course, which is pretty good and gives me a bit of a boost, and Red Bull which is about the same for me. Neither one really gave me any spectacular energy, but they are both pretty tasty. Java Monster is the first energy drink to really give me any noticeable energy boost.
