drink generously? no need to go overboard. Just set a couple bottles of water by your computer at night while you're doing whatever, and sip on it. Aim for having the bottles empty by bedtime.
I sip on something all evening long, and then drink a full glass of milk before bed. Has done wonders for my sleep, and always insures a moderately wet diaper by morning. (4-6 wettings typically) I wake up frequently overnight, so getting back to sleep asap is important to getting a lot of sleep overnight. Not having to make a potty run across a cold floor to a bright room several times a night has been a great help. So if I wake up and have anything noticeable in my bladder, I wet my diaper, then go back to sleep. Repeat all night long, every night. You don't have to wait until your bladder is bursting or even full, just empty out anytime you wake up. Works out better for your diaper also, less chance of leaking if you don't flood.
Looked at from another angle, if you like wetting your diaper, you'll probably enjoy more smaller wettings than fewer larger ones.
