Hi
My low point was day 6, I could have eaten the leg of the table but that may well have been as it was a Friday which I've always looked at as start of the weekend and time for treats. OH and I went bowling instead and I got through it.
If you can, maybe try to focus on it just being that one week that will be difficult for you and try to fill your time as much as you can, break habits, do something new perhaps. I think keeping occupied is half the battle.
Good luck, hope you manage to overcome week one.
