Hi! My story is similar to yours (except for the pregnancies). I started out last fall at 366, and am now down to 313. I definitely noticed that I feel better.
I'm in the process of losing weight in order to
get pregnant. We tried to get pregnant to no avail last year, and then I decided that losing some weight would probably help out in all regards. Well, I do feel that losing some weight did help me get pregnant (I got pregnant in November, but the little guy decided not to stick around

). I am going to lose some more, so that I can give the next baby a better shot when we start trying again. I definitely feel like the weight loss boosted my fertility, and I was able to get off of my hypertension meds too.
Sorry this post went so far off topic. Congrats on your weight loss.
