I think you will really enjoy Curves. It's a lot of fun, and you get a lot more support there than at a "regular" gym. I joined there at the end of January, and so far I have lost 13 lbs and 10 inches (all over). Stick with it. You can do it!
I'm sorry to hear about the time apart you have to spend away from your husband. I know how hard that can be. Keep your chin up. I'm sure it won't be forever. It can be very lonely, but you will be okay. Keep going to Curves and let him see a little "less" of you every time he comes home.
Take care, and HUGS to ya!
