NEVER tell your Friends and Family you are going Sugar Free.
I see this come up a lot on here about how people tell there closest friends or loved one's they have started a Sugar Free journey and then it ends up causing problems between you and them. They will deliberately start trying to give you Sweets and Chocolate etc and if you refuse then it's a bit of a problem. They don't like it. Most of your Friends and even loved ones are going to try and sabotage your Sugar Free journey. It's a harsh truth... They don't want to hear about it and I reckon its because they don't really want you to change and better yourself. They may fear you will become a changed person and thus making THEM feel very inferior about themselves. It's the exact same thing with people who want to go to the gym and build muscle or even lose body fat. I've heard this over and over and over again and have even experienced this myself. I'd recommend everyone just keeps the "I'm going Sugar Free" to themselves. You'll be glad you did.
And also not every single person will try to ruin your progress. Some people will genuinely care and hope you succeed but honestly they are pretty darn rare. I hope this helps some people. Even if it's just a few. Good Luck.
