I posted before I read the other posts. Come back and read the advice - great advice from people (and support)!!
One more thing - there is this thing that I had on my computer at work and here at home called - the quit meter - it tells you how much life you've added - how much $ you saved. That helped a lot to and my daughter loved seeing it.
If you do a goole search for quit meter it should come up. If you are on the computer a lot it's definately worth getting (it's free)
good luck again. We can do anything we make up our minds to do!! : )
