Is there another way besides paying a damn priest 750gp per character afflicted?

Take your own priest and use The 7th level priest spell "Restoration".

Jaheira doesnt have access to level 7 spells yet, and neither does Aerie. I would gladly pay the 2k to cure the three people in my group of it, but I have to go back into the graveyard anyway and will probably get energy drained again. I am on Act 2, am I jumping too far ahead by venturing into the graveyard? I killed the spider chick in the web room and slaughtered all the undead in the egyptian room with the trapped floor picture of a pharoah. Should I just forget the graveyard for now?

Aerie has access to a spell called Lesser Restoration - which is a level 4 cleric spell.

It should cure your level drain but not heal all your life - which GREATER RESTORATION does.

I hope I helped ya in some way

You helped in many ways. Thank you.
