mooseman has some good ideas with the water. that's what i do for the morning shower routine when it's freezing outside.
Also, as mentioned before, you don't need electric blankets as they are a huge drain on power nad i've seen my share of people getting burned or fried by them, don't ask how, but they did. I personally go with a soft mattress pad, covered with flannel sheets and a huge comforter at night. The comforter was kinda expensive, but it does save quite a bit of electricity and the wife will like it
towels under the doors or buy those rubber doorsweeps. most aprt doors have massive gaps underneath. You can buy eihter foam weatherstripping in lowes or home depot or buy the insulaation kits at walmart. anything that reduces a draft is going to help.
I do live by the ceiling fan, just set it to blow down and it keeps the warm air down where you can feel it. set it on low, though, after it gets moving, the air continues circulating w/out feeling cold.
