I'm on the se situation . 3 years out and lost 60-70 depending on the day. I finally went to the dr and am on phentermine and using the my fitness pal app. It has helps me tremendously. I've lost 11 pounds in 4 weeks and only have 10- 20 more. My fitness pal has really been a god send and it's totally free:)
I'm 3 years out and have the burping sounds still. It has gotten better with time but still does happen. You get used to it and as time goes by they decrease.
If you hiccup it's because you are too full. I had the same problem. I still get them 3 years later if I over eat. Adding sugar isn't the answer:) good luck!
