NEW TO OH...Hello!
Welcome! For me the worst part of all of this was the liquid diet, so stay strong and remember why you are doing this and stay focused on that. Make sure you take your measurements because somewhere down the line the scale is not going to move and this way you will be able to measure your success in a different way. If you haven't started yet, you might want to start walking or doing some kind of exercise, it will help you with your recovery. Right after surgery, moving helps to get rid of the gas that they pump into you.
Good LUck!
