I honestly don't know how you guys do it. I quit reading stories in parts years ago. I could never stand the tension
I don't know how I do it either. I almost never read wip's (or even completed stories being posted chapter by chapter), but every once in awhile one story will catch my eye and suck me in. The fact that I have three of those such stories going on right now does not bode well for me. Drives me a little crazy

(But, of course, I love all those fics and can't seem to quit them now...)
