I went to a dietician and she asked the usual questions.

As a veggie I was (and still am) pretty proud of the way I eat. I could see her mentally scrubbing out her normal advice as I seemed to eat pretty carefully - not snacking, conscious of wholefoods, five a day - all the boxes ticked, not even huge portions etc etc.

Then she looked up from the page and said "What about drinking?"

"Aha" I confessed, "Got me there!"
