I have to say until I started this journey in January, I lived on diet coke caffeine free. It was the only thing I would drink. I bought 24 cans at Christmas, and started this LCHF on 3rd Jan. I have only just drunk the last can from those I bought before christmas. I would have drunk them in 2 weeks. Bottom line is I have changed, I actually enjoy very weak no added sugar squash. I can't stand plain water...but I've dropped the fizzy and only have tea and squash. It's amazing how this diet changes what you enjoy.
