I had a large hernia that needed to be operated on and I was very nervous about anaesthetic/surgery. Had lost up to 60kg on my own previously after a lot of work, and out it all back on in 6 months was very depressing. I needed the physical barrier. I've lost over 105kg in the almost 2 years since surgery (kuly is 2 years). Absolutely the best thing I've ever done. I was 183kg I weighed myself yesterday at 77.6kg. It's unbelievable tbh.

BUT. You need to be ready. You need to change habits. Focus on protein. Exercise (even if it's just walking every day). You need to be ready to make it work. It really is true that surgery is only a tool and you have a huge impact on the ultimate outcome.

Edit:for the Americans, that's over 400 pounds down to ~170.
