I agree with everything Trina just said.
I am post op. I had surgery in October and I am down a total of 74 pounds including 28 I lost before surgery. This is a lot of work but worth every bit. I would recommend this surgery to anyone who is willing to put in the effort. In four months I only had one moment of regret. I was having a bad day a couple of weeks after surgery. I had a little tiff with my husband and I really wanted to emotionally eat. I couldn't of course because I was still on liquids at the time. At that moment I regretted getting the surgery. The next morning I was soo glad that the surgery had stopped me from overeating the night before. I have not had a moment of regret since. There are times when this process is frustrating and difficult but I know in my heart that if I did not get it done I would not have lost the weight.
Here is another website to check out.
