Hey jen
Your doing fantastic. Im not on cambridge that long and got into the same rut two weeks ago eating biscuits crisps, had two take aways but have lost the weight I put back on. You need to look at your old photos of when you had the weight on and take a picture of how you look now if thats doesnt encourage you to loose the weight I dont know what will.
Do you have any holidays weddings etc coming up soon, why not set yourself a mini goal even losing half a stone can make a huge difference to how you look and feel.
My finace just booked us a week to skiathos in greece flying out on the 11th, my goal is to loose a half a stone before then (2weeks) which is possible if I put my mind to it.
I 've completly changed the way Im doing things, got back into drinking the water, started swimming classes last night which I havent done in 5 years and aboslutley loved it (although didnt like people seeing me in a swimsuit) also started getting off the luas (tram) early and walking the rest of the way home (30 min walk).
Just see the last week or so as a blip. You'll feel so good when you reach your goal and thats priceless and better than any packet of chockie biscuits!!!!!!
Go girl
