Jaxsi,
Here's a list that I've compiled from various UK hospitals. It's a good starting point for what you can/can't eat and drink. But, as everyone's saying, it's different for us all. Keeping a diary can really help; try new things one at a time for 3 or 4 days on the run; small meals and snacks throughout the day. Best luck.
