Thanks for all your comments, I start the pre-op diet tomorrow which is 5 portions of both carbs and fruit/veg and 2 portions of both protein and dairy. Then 2 weeks before surgery I start the liquid diet. I only found out about the liquid diet yesterday so I'm trying to gather as much info as possible about it in order to prepare myself mentally.
Big hello Chris, it's good to know that there's another family member that understands, we can support each other (even if it is over 200 miles) xx
