Hope your DD feels better soon, Neros, tonsillitis is awful. DH had it over the Christmas period. He was trying to trump my abscess, he does it every time! 
On New Year's Eve, we were both on strong antibiotics so no drinking, we went to bed early as we felt so rotten, and his snoring was so bad I exiled him to the spare room! Great start to 2020

Wreck is anyone around to give you a hand? 
Hope you're feeling better Crazy. No point beating yourself up over a gain. It has just been Christmas and you said yourself some of it will come straight back off. I found combining mindfulness (as per Wreck) with calorie counting on MFP really effective to lose weight, it makes you really think about what food you're eating and why you're eating it, in a way that SW doesn't. And that was a big part of why SW wasn't right for me. My 'full' meter doesn't work - because it was 'free' I'd give myself the same size portions as DH, who's nearly a foot taller (including veggies, because I like veggies). When I cut my portion sizes right down by half, I still didn't feel hungry after eating a meal, and I lost weight. On SW I'd eat fruit because it was free, when actually I wasn't hungry, just bored or emotional.
When I had a limit to my daily calories, I'd think 'that apple/chocolate bar/biscuit is the equivalent of rice/Poppadoms to go with my curry at teatime'. Then I'd make a decision whether it was still worth it. If it was, I'd eat it.
