Sounds like your energy level is down from having been sick. You need to ride enough to rebuild some fitness. Look at it like putting money in the bank, only at this bank, the rate of return is really good.
Oh, and the "scheduled ride" part. That would make me sick. Other than signing up to lead rides, out of hundreds of rides over a five year period I don't think I ever "scheduled" one. Having said that, I couldn't wait to get on my bike whenever I could.
