I, sadly- very sadly, would have to say that if you are losing weight (and that is a considerable amount, not just 2-7lbs) than some would tend to think you CAN do this without surgery. I am not at all suggesting you quit losing, just pay close attention to the facts. If you are like me, you have lost weight before and it will more than likely return. Do you want to keep yo-yo'ing on the diet torture or do you like most of us here see this as our FINAL opportunity to be "normal" and not have to sleep/eat/drink our addiction constantly- thinking about whether or not you should have had that last piece of bread or a glass of wine??!
All I hope is that if you can lose this weight w/out the surgery AND KEEP it off- than you should continue losing it naturally. If you know better, than you have to make another choice - stop losing weight??
I wish you all the luck in the world, I feel your plight!!
