Congratulations! You are doing your health a huge favor! We have a reliance on pills these days (doctors included) to make everything better. They have their place, but I bet many people could get off them, as you have.
I'm not sure it's all about sabotage. You nailed it when you described eating as "recreation." Friends, family want to celebrate, have fun, whatever, with food. And, they want us to join in on the festivities with them. I think we are just wired that way. Your abstinence just reminds them of what maybe they should be doing to improve their health, but choose not to.
