FWIW I don't feel "wired" either, but I have to say that I am now able to get myself into the gym every day without much of a problem. Whereas before I found myself skipping days. So I guess that would have to count as some sort of an increase in energy.
On the other hand, I've also noticed that now I seem to do better with a full eight hours worth of sleep. Prior to LCing I could easily get away with six hours.
Go figure.
