Ooh glad I've read this. I'm really struggling to drink jsut water. I knew it would be a problem and asked consultant on Thursday if there were any drinks I could have that didnt contain citric acid, but she didn't know of any. She told me about the orange powder drink they do, but she didnt have any in stock. I would LOVE to have a little drink of Dr Pepper Zero, especially at night when I struggle the most. It would feel like a treat. And if it doesn't contain citric acid, it should be ok I pressume? Shall I or shouldn't I lol....
