Thanks for the support everyone, that's why I love this thread 
The hotel didn't have a pool or a gym, and we didn't really walk much either so the exercise for the long weekend equalled zilch, despite the fact that we should've done the first day of week 3 of C25k... Just couldn't face it with a hangover!
Got back yesterday and ended up with a McDonalds AND a Dominos, I am so ashamed but it was quick n easy and we didn't have anything in 
Oh well, back on it today and I'm really trying to sorta detox, though I feel like 'detoxing' is a bit of a con thought up by the dieting industry!
So far today I've had two cups of green tea with lemon, 30g Special K almond & honey and I've just made a huge batch of tomato and basil soup to take to uni with me. My body is still feeling a bit iffy after all I ate over the weekend but on the whole I feel much better. Going to exercise lots too 
Crunchie, we'll be fine
Saturday seems like a long time away, enough time to do some damage limitation anyway!
Well done on the losses flatmouse
And welcome back sally, so glad to see your name pop up here!
Fled that's a great start considering you haven't been out since Oct, I'm on week 3 of c25k and running for 3 minutes straight seems daunting!
Glad to hear everyone's exercising, that's going to be my goal from now on.
