I also work out of my house and travel sometimes every week a few days or don't travel at all. It made things easier with my 'drinking' as I could easily hide it and hide myself away from the rest of the world. I could start drinking at 1pm and no one would be the wiser. I got away with it but now, I hold myself accountable and just don't go there. It hasn't been easy - its been hard. But I'm 13 days in. If I can do it, you can too!
I'm 41 so this lifestyle has been there since I was 30 - working out of my home. But now I'm trying to fill the days with other things.. cooking, cleaning, reading a book, trying to stop old habits by going to the gym, walking in the park, getting out of the house more. Maybe its about changing habits in the beginning? But its working for me.
Good luck with it and let us know how you are doing!
