Ali - we must be on the same wavelength here! That's great!
I, too, am going to lose around 80 pounds this year with no two ways about it - it WILL happen

and I AM doing it. The year will trudge on whether we lose weight or not so we might as well lose it. Carbs made me feel like total crap, too. I think the proof is really in how you feel on the diet. I will start week two on tuesday and I feel pretty damn good myself. Less mental fog, more energy, etc.
If you haven't already started a low-carb thread, I'll start one and we can swap recipes and how we're doing.
we can DO THIS!
