Well, I just realized yesterday that I have enough mana regen that I can grind infintely without needing to drink or use SoW. I'm pretty psyched :) Lvl 65 Holy Pally.
Start out with JotC, SoR, and judge SoR 2x (once at mobs 50% health, and once for final kill). I end every fight with full mana. Throw in a Holy Light when needed, but it regens right back during next fight.
Of course, if I get jumped by more than 2 mobs, then I have to use other spells...which in turn makes me either use BoW or drink.
I know others have been there/done that, but I haven't. Just a little happy note :)
