We are also on the 7 pm to noon plan and it works better because at least you have the morning before noon. it is going to be harder though as it heats up this summer. last summer I was pregnant and just accepted the outrageous bill for the AC as there was no way I could tolerate the heat. It is unfortunate that it is so expensive no matter how careful you try to be! But I think this plan might work better for you than the one you have now...
