Great replies - thanx!

I have considered that this is just a fluctuation, but given my past history of being so fat, I'm a little scared of gaining much weight at all. Obviously, I want to gain muscle and know that the scale will move, but it's just a little weird for it to happen in one week.

I'm going to go with how I feel and how my clothes are fitting on this one - which is good on both fronts. It's just a little nerve-wracking!
