I drink far too much diet coke - usually 3 cans a day. I went for 3 weeks without any at all last year and felt loads better for it - more energy, less bloated. I had a mild headache the day after I stopped, but after that felt ok (did miss it though, especially at lunch time at work). However, I started to have the odd diet coke when I was out, which quickly became my usual 3 cans a day.
I drink diet coke because I like the taste, like/need the caffeine fix and I guess it's a habit that I've had for years.
I know it's bad for me and I think it's time I stopped. Would anyone like to join me? Please, please, pretty please? Think I will need encouragement to do this for good!
