Love your optimism, Pat
Generally post hols it takes me about 3-4 weeks to get back to the 92kg or so range and given my natural size and my refusal to diet or significantly reduce my alcohol intake that's really the best I'm going to do.
Exercise 4 times a week, eat healthy breakfasts and lunch as much as possible and try to limit my drinking Mon-Thu is the best I can do so 92kg it is.
