Hi all. A bit of pertinent background: I've been playing pool (mostly 8-ball, 14.1, and a little 9-ball) off and on most of my life. For stretches of a few years, I'd play every day for at least an hour, often more. When I played all the time, I got to the point where I could run an 8-ball rack about 1/4 of the time, and the odds went up sharply if I got another run at the table. I was even confident enough to make a few friendly wagers with the regulars in the pool hall I most often frequented, and I usually played better under that pressure. Hell, if any of the regular staffers were behind the counter, I even had my own walk-on song playing by the time I hung my jacket up and opened my cue case. 
OK, I realize that probably reads like some rosy reflection on some terrible pool player's glory days, but I digress.
My problem is, after a few years of poor health (still not 100%), I tried to get back into it a while ago. I joined a novice bar league with some friends, and after about half a season (with practice in between), my performance got measurably worse while the league stats improved. Missing frightfully easy shots, averaging a meager 1.3 balls per turn, with some flashes of relative brilliance but mostly just inconsistent play. I was stone cold sober, and couldn't beat some of the worst drunks in the league most nights.
It was the downhill slide that finally prompted me to give up my spot for the sake of the team, not to mention my own sanity. Maybe it's a slump, maybe I'm way more out of practice than I realize, maybe I was never that good to begin with, who knows. But my confidence has taken a hit, and this whole thing has even (*gasp*) tarnished my love for the game. I want it back, dammit!
I know some of you have been through similar things. What helped?
