I have had the same problem getting restarted on this way of life now i have been on two whole weeks. I think the key is to plan....have lots of legal foods.
I love bacon, the first few days i eat a lot of it...maybe its the fat but it helps the hungrys.
Plan out the 1st 3-4 days with lots of yummy meats and get a low carb dressing you like.
Also it helped me to tell my boyfriend that this was important to me and please no ice cream in the house until i got stronger...and don't offer me pizza. I told him I have trouble saying no and needed his help.
I also removed my mindless snacking foods chips, popcorn etc.. out of my roaming hands reach.

Now I am doing great...It gets easy

Good Luck I hope this helps
