Everyone is different, but here's mine
No NSAIDS (ibuprofen, Advil, Diclofenic)
No Chinese food (MSG is a killer)
No smoking (but I still do!)
No alcohol
No red meat
No nuts, popcorn, sweetcorn
Lots of Paracetamol, Codeine, Entocort, Pentasa, Cyclizine, heat pads, rest and some more rest.
Plenty of knickers, bum cream, wipes, to take out with you.
Dioralyte, Ensure, water, bananas, Your gastro and GPs phone numbers,
All packed in a rucksack in the car!
Prevention rather than cure!
