I also felt the need to chew something. And I was only a week out from surgery and I ate 1/2 a biscuit. Yes, I know it was wrong. Yes, it hurt like Hell. And no - I won't do that again for a very long time. I did not do any permanent damage but it did scare me enough to put me back on the straight and narrow. I just keep reminding myself that I have been heavy almost my entire life and I must re-teach myself how to be healthy. I have 2 little ones at home who depend on me and I want to see them grow up, graduate, get married (if that is what they choose), and whatever else their lives hold for them. So listen to your body and I promise, it does get a little easier. I am 4 weeks post-op today and have 2 more weeks left of my soft/full liquid diet. I have just filled the time I used to spend eating with walking, or research and my work, which I love. It also helps to have someone to turn to when you get these urges. Your support team is super important. My doctors office nurses all gave me their cell phone numbers that I can use if needed and that has done wonders to relax my fears.
I wish you the best and hope your cravings get easier. Good luck!
