Where I work we have shared lunches all the time and celebrate staff birthdays with spreads of cakes and goodies. I straight off the bat told everyone I was quitting sugar and they were really positive. They wanted to know the ins and outs. They still offer me "tastes" of things but once I say, honestly I really don't want it and I'm not just saying that to be healthy... they are good with it. I guess people associate a lot of love with eating together and they don't want you to feel left out. I am not preachy towards them but I am bringing in fructose free treats and everyone loves them.
I find when it comes to drinking situations, just have a glass of soda water in your hand. People just assume its vodka or if you do want to drink than there are options out there.
When we go to dinner I do ask the waiters questions and 99.9% of the time they have no idea but they are always accommodating and will change out items at my request. I think its your attitude that helps. I make sure I always compliment the food first, "Oh wow this lamb dish looks amazing, would it be possible to have it without the sauces and could I also ask for some extra vegetables etc. They always say yes. I do also try and dine out earlier when there isn't a thousand people waiting to be served so that I'm not stressing out the waiters with my questions or you can even ring up ahead of time and ask for the menu and sprout off your questions then.
Just be positive about this journey to your friends and colleagues. If they can see you are enjoying this new way of living they will want to bask in your happiness too. If they think your suffering and its too hard, then they will try and coax you back into the world of sugar thinking they are helping you out!
Good luck x
