Anna,
I'm so proud of you!! It will not be easy, I'm sure, just like quitting anything that you enjoy, but I'll bet you will be able to do it!!! Get out with those pups when you're at home and maybe you can get at least one person at work to support you in this and perhaps quit themselves!!!
I will keep you in my prayers and hope that your will power and strength to do this will carry you through!!
Logan
