I too think that 'tradeoff' is such a better word.
My mother isalways at it with "having to sacrifice this and that", but I don't like that mentality. Truth be told, I've cut down on processed foods and other artificial sugars, and I don't even miss them a lot--which probably wouldn't be the case if I was spending everyday thinking "oh woe is me I am SACRIFICING tons and DEPRIVING myself". It's sure not easy, but I honestly think that part of all of this is in our heads only, and departing with a positive, strong-thinking attitude is IMHO a good key to success.
Anyway--This sounds like a good plan you have here. I won't say good luck because there's very little left to luck here, but I hope everything will work allright for you.
