I'm hoping to go until Christmas but I will definitely continue until Dec. 13th. I have a gathering with co-workers on the 14th that I've been planning for about a month. So I know that day is a day for feasting!!!
I can relate to your situation. Luckily my ex moved out a few months back so I can keep my cupboards and fridge empty ('cept for the fruits & veggies I juice) - grocery shopping is torture! But when he was in the house I could usually go for 4-5 days at most before I'd cave in. Working overtime saved me most of the time. Then I'd come home and go to bed as soon as I got my 'chores' done.
I know I'm capable of doing this because I've done it before. It really does help to have the support of others going through the same thing. Friends an family never like to hear that I'm fasting.
Well, I'm off to weigh myself-
Have a great day!!!
