Dear lovingit- please don't be dismayed! There are many (I mean MANY) factors in your 'numerical' weight loss. See if I had given up all the things I loved and didnot do weights at all I probably would have lost like a 100 lbs in the same period- and then would be sitting again under the knife to get the tummy tuck. Allow your body to adjust slowly to the new you and all the while continue to tone yourself so you don't end up looking like an unhealthy skinny person- but a firm, toned, no second operation needing yourself! Also note that some of those people you are talking about who lost 130 pounds- started at 300lbs too- so they will lose more much faster than you or I would. Because I started at 248 of mostly flab- and my goal was to get to a toned/ built 160-170lbs, I have started losing less and less- but that it is not necessarily bad- b/c I am replacing flab with muscle.
Keep your chin up and stay the course. This is much like investing in your retirement plan. You cannot put in a million bucks one time and expect to have a nice nest egg (you may have bought at the wrong time!)- so you want to keep putting aside a few bucks but do it regularly-and in a while you will look back and say- "damn!"
