Heh. I've been in the same situation - at one point I had ten games going, and it started to take most of a day to play them.
Never again, says I, not even when I'm unemployed with time to kill.
Have you considered getting into just one or two games? Maybe ones that are on a 48 hour schedule? I've found them to be pretty sane and relaxing, since even in the late game, you're only talking an hour or so every 2 days.
