When I started to work from home (after 15 years in a office), I thought it was impossible! The minutes (the hours) flyed away between a cup of coffee and a phone calling to my daughter or my mom. I could work better in the night, but it was (I was) crazy! After 4 years now I'm more "diligent" :D
I suppose you eventually get used to it! Ah well, in 4 years time I will be laughing :O)
