I got a promotion! I am so happy! I will be quitting my in home job and picking up more hours at the Fitness Club!

I get a raise to compensate losing my job from home and get more hours. And get to come home earlier at night. instead of being home between 9 -10 pm I will be home from 7:30-8 and get to tuck my children in bed and read them bed time stories now! yippee!!!!
This starts next week and I am so happy! this means more amily time at night and more money to get some bills paid off!
Now the only problem is quitting my job. when to do it. Should I do it now or wait till Friday when I have no more shifts for the rest of the week? Or give them at least the extra couple days notice? Any suggestions????
