Well, I watched two episodes of the set per week. So I'd just rewatch the old episodes throughout the week. Usually right before bed. Also, I watch it with my girlfriend and my friend. So that's two (or at least one) extra viewings right there. One Piece is a nice thing to go to sleep with.
Also, I multitask while watching.

God, I can't even tell you how many times I'm going to watch this coming set. You don't want to know.
For me, only Tsubasa's Acid Tokyo Arc comes anywhere near Water 7 in terms of phenomenal arcs. And even that isn't all that close.
I'd really recommend that series, but clamp's art style can be a bit messy. And the story gets convoluted, great as it may be.
Awesome and I sometimes watch one piece with my girlfriend, she seems to like it quite a bit. I really don't blame you for watching this set over and over, I may watch it as soon as i get it and then again on christmas eve or something. I am currently reading Tsubasa and it seems pretty cool so will defenitely have to keep going with it if you beleive it is in the same league as the mighty water 7.
Incidentally this is Stephanie Youngs latest facebook status( though i'm sure many of you may have seen it)
"Still a bit emotional after our One Piece session today. Robin is breaking my heart! We have a band gig tonight, but afterwards I need to curl up on the couch with a blanket, my guy, my puppy, and a cup of tea. Things are getting DEEP!"
! Seems they may be up to the infamous "I want to live" part.
