Brit in Oz

STRUGGLING! I'm so close to my goal but really struggling with the last 2.5kgs. It doesnt sound much but I'm terrified that I'm going to start self-sabotaging. I've been literally walking my butt off and being so, so careful with what I eat but now the thought of maintaining this huge loss is seeming like a massive mountain to climb for the rest of my life. I've been here so many times before, not with weight loss surgery though, but we all know that the surgery is just a weight loss tool and can be circumnavigated easily. Anyone have tips on how to get that last bit off and keep it off?
