You know, now that you mention it i have that also. Last night i had a med mania going on and i was WAY to hot so i was working in my T shirt. This was during the time we didnt have heat in the house and it was in the 20's outside. (waiting on a fuel oil deleviery, everything is good again)
SO i am having a med level mania and end up cleaning the kitchen like a lunatic. Thank god the dog doesnt judge me, he was just hanging out getting leftovers and treats. LOL LOL LOL
And when i get depressed i get cold, so does my wife also now that i think of it.
Good job, you might be on to something here. At least it might be anoter warning sign to be on the look out for.
