I can't sleep without my comforter either.
67 degrees is too cold for me, too. Setting the thermostat at 70 in here during the winter isn't warm enough for me either, but that may be our thermostat or the building. IDK.

I'm glad that you feel comfortable enough to increase the lithium. I hope that the new dose, and the new dosing schedule works out del for you.

How do you feel about the Lunesta? Do you have a history with it?
