I know it isn't very good for you, but would I be ok to drink it while otherwise following all the rules. I think if I can have diet coke, I will be able to cope with cutting everything else (sad - I know). It is something I definitely want to get rid of, but it is a bit of a crutch for me. I drink plenty of water too, and only drink tea/coffee occasionally - so no other caffeine really. I don't have a sweet tooth in general, so don't imagine it will send me into a sugar craving spiral??
