I don't know how hernia surgery would affect you, but I know that when I had a laproscropy before it took months for me to fully heal from that- and it was just a couple of tiny incisions! So it could be that that has affected you or the way your abs are affected. Have you tried working the abs and back or gone to phsycial therapy?
I would be happy to see my boobs get smaller. I am wearing a DDD right now and it is hard to find decent bras and so forth- Lane Bryant is the only place I can shop. But I suspect I will always have large boobs. I was wearing a D cup in the eight grade, for instance. I remember back then I was terrified they would never stop growing and I would have to wheel them around in a wheelbarrow.
I noticed stretch marks before too. At first I thought it might be some sort of infection, but nope. Just plain old stretch marks. And I remember back when my belly started to really expand on its own, after I got above 240. My fiance noticed it and asked if I had gained weight. I said yes, I had, and he said ok and just kissed my big fat belly. I knew he was a keeper then.
