Thanks everyone.
I think I'm going to try and be at least a little bit good on hols. My last holiday, and the Xmas, I completely let loose and stuffed my face! I feel like I can still enjoy my holiday away (in Padstow) whilst having some healthy meals too.
Hopefully chances to get out on some long walks will help too.
Crappy day at work today. I really am not enjoying my job managing others. Been sticking at it for 2 years now hoping I will grow to like it, but can't help but think I need a completely new job. I am reducing my hours next month to do a bit of a different role in a similar department so maybe that will help solve things
