the first place you want to lose is the last it seems. nature's funny on us.
sodas are full of sodium and sugar.
goodness, what else? chips, all those sort of snacks.
just cutting out snacks help a lot actually. once you get used to it.
walking when ever you can. and as you say, water is good for you. helps flush out the bad stuff and replenish your body of fluids you really do need.
good luck hon. :thumbup:
