I too have the a/c set to 72!!! I even drop it down to 70 sometimes. Of course, I'm so afraid of it freezing up on me though. I have 1 ceiling fan and 2 stand alone fans. I have them running too. Well, I turn the living room fans off at night and turn the fan in my bedroom on when I go to bed. I also have been showering before bed as it cools me down and helps me sleep better. I have been doing that for a while now and it really helps.

I am now in hibernation and will come out only if necessary.
