You go girl !! I AM one of those who whines over the 15 PLUS lbs I've gained - and I can tell you ...after we women hit 45 it is HARDER TO LOSE....
I don't know how old you are but your metabolism is FAR BETTER when you are younger than it is when you get older...If I was to diet right now at 46 it would take 3 times longer to get it off - I tried to lose 15 pounds a few months ago and failed miserably.
My Incentive to you is - LOSE it now if you want to - you CAN do it ...and don't wait till it gets even harder to diet - If you have the will-power and want to do this - YOU CAN !!
Good luck and I'll be cheering you on
