Wow, I was never restricted, and I think I turned out okay. Never knew that soda was so Taboo...
I definitely wasn't allowed to have any in my lunch until 8th grade, my mother always gave me some kind of juice, but I always had a glass with dinner. She didn't want me drinking too much, but it was okay with one meal.
I will admit, I have an obsession with Coke from the fountain. I like it so much better than the bottle or can, at college I love going to the dining hall, sometimes I'll take coke back to my room in a coffee cup to go, lol.
Growing up I drank alot of calcium Tropicana OJ or Caffine free Coke. Being a guest in someones house when I was a teenager, I would never expect anyone to restrict me to just a can of coke. I do believe I would have been a bit offended if anyone tried.
Perhaps it's where I live, but I never heard of anyone doing that. At parties it was always readily available, with no one cutting off the supply.
