Codiene can make the pain worse! Something to do with it causing sphincter of oddi dysfunction. Stick to Naproxen and Paracetamol but most importantly Buscopan.
I found taking all the meds at the very first sign of a twinge and lying on my left side helped a lot.
You can't have mayonnaise. It's literally oil and eggs
I ate a lot of homemade soup (and cuppa soups!) Pittabreads with salad, roast chickpeas, baked sweetpotato and beetroot mixed in with green salads or cous cous/ rice salads
Prawns are really low fat surprisingly and I ate a lot of smoked haddock and new potatoes.
I used vegetable stock to cook things like potatoes to give them a bit of flavour instead of using butter, and I used plenty of herbs.
I used 0% fat yoghurt to make some lovely dressings - it's one habit I will definitely keep.
I was absolutely fine with alcohol, spice, tomatoes, onions caffeine and fizzy drinks.
Chocolate, cheese, cream, butter, mayo any oil, red meat or anything not 'green' on the fat content on the packaging 'traffic lights' were an absolute no.
