I try the get my wife and daughter to still have their snacks although we all eat much healthily now.
Christmas was hard. Very hard. It's my first as a type two and wanted to be good. Blew it a couple of times and had readings in the 13.5 area. But back on track now.
Don't try to get everyone to eat the same as you, just try to resist. Easy to say, hard to do.
