You really want to make a change in your life and thats a good thing .. I agree with Kaliope try and find some more things to do in the afternoon so that you can avoid the "down times"

When I find myself in the same boat I will re clean my house I can reorganize my dishes ( kinda sends hubby in a tail spin trying to find a damn glass) or organize DVD's ..read a book, new hobby maybe? and Surf PC and just pick a topic and learn more about it.

I feel your pain I go through the same things at times..it sucks !
