Hi Lindy,
I am also on day 4.  Think yesterday was my best day.  The day before I was a nightmare!  I kept looking at and smelling food!  I was being such a pain, I was hoping someone would say.... "go on then eat"....... then it wouldn't have been my fault! Twisted logic or what?  Luckly they didin't and I am so glad I stayed on track.
Feeling really positive today.  I said I wouldn't weigh myself all the time, but  I think I have weighed myself about 50 times this week!  I have lost 5lbs in 4 days - but I'm not going to get too exited just yet!
Good to hear you are doing well too, let me know how you get on.

p.s Think I will start a new thread about the chewing gum!
