As far as those details:
My impression of the camera flip was that gravity plane changed and they were now upside-down compared to before, but Trek ships usually keep gravity in the same plane for all decks. If it wasn't that then it was just plain confusing.
As for the "go-juice", I read it as a take on what they called "the tick" in David Weber's Path of the Fury books. It was a special drug that Marines took in that universe that increased the speed of your data processing and thinking capabilities, so that you had all the time you needed to consciously recognize and react to your enemy's moves and movements. Beating the Klingons makes sense to me under the influence of that, as they could see each strike the Klingon was about to do and had plenty of time mentally to see it, decide how to dodge or counter it, or what openings the Klingons had to strike, and then move to strike before the Klingon could react properly.
I'm sure Weber isn't the only one with something similar of course, but unlike the Shadowrun equivalent, it doesn't make you move faster, it just lets you see and decide what to do. It makes -every- movement purposeful, and that was how they seemed to be acting. Of course in the Fury version, when the user comes down off the Tick, they usually end up puking their guts out, so that does make this a little -too- clean here... maybe it has addictive properties in the Trek version, and that's why we don't see Starfleet Marines riding the tick all the time?
