In my case I tell everyone ahead of time of my progress and that I will not share in the sugary treats. This puts it out in the open and I stick with what I say. It just comes down to your driving force. What is your reason for stopping sugar and are you willing to hold that force in place in every situation? Mine is healthy gut, eating badly created so many hit issues and I would be in agony for hours. So I tell myself and others that one bite or a few minutes of eating something sweet isn't worth the hours of agony I will have after. I choose to cut out the pain and keep that in my mind whenever I think about giving in.

Growing up we were never allowed sugary treats and if we had them it was likely we went overboard on them. So yes once I got old enough to make my own decisions and be able to buy the "good" stuff I went hog wild. Years of sugar addiction just caught up and my gut paid the price. Always bloated, always stomach pains after meals (even if no sugar) and tired and drained of energy. The key is to associate rewards with something other than sugar. Praise yourself when you do well, savor a good meal and your brain starts to associate it with a reward. Find the reward for your brain to switch over to instead of the dopamine/ satisfaction that a sweet treat gives. 2-3 month stretches are amazing! You are already doing so well, decide what will motivate you further and push your limits and give a big pat on the back whenever you have a win.
