C4 - I also concur with option 1! Enjoy it, don't gorge, and start back on the woe properly in time for bootcamp. I am having a milestone birthday fa couple of days after the start of BC and I'm planning to do something similar.
I had my "reward" massage last night and I kept visualising the masseuse bursting fat cells (she used quite a lot of pressure) which I'd then flush out but a quick google shows this is entirely fantasy and massage does not particularly aid fat loss, ha! Annoyingly I'm up a lbs today. I'm very close to being under 80kg, another 2lbs to go and it's moving in the wrong direction for no discernible reason. As I've always weighed in kilos (metric system growing up), 80kg "means" something to me in a way that lbs, let alone stones, really don't. On an emotional level, stones are completely neutral for me, which would be a good way to measure if it wasn't so bloody complicated :-)
I've been drinking too many milky teas and diet cokes, and not enough water, so planning to tackle those on strict BC next week. It's shocking, but I don't think I've gone 2 weeks without a Diet Coke since I was a teenager. Curious to see if it makes a difference.
