To reduce my Pain and discomfort I eat as healthily as I can i.e. 75% of my 1 plate per day is dark green, i snack on fruit, bananas reduce cramps, I eat 100% whole grains and drink or consume as many super foods as possible ie pomegranate, blueberry, dark green veg ... Also figs or anything that's good for stomach health. Stomach health seems to be the key to pretty much everything, apart from your hardware.
I know changing your diet is a pain in the ass lifestyle change, but its preferrable to pain and misery. ALL YOU CAN DO IS BE ALL YOU CAN BE ! Banish those toxins that are constantly at the door.
A super greens drink is a reasonable option but NO replacement for a ton of real spinach and brocoli.
Avoid anything 'nice'. It'll be rammed full of sugar, salt or processed or spicy.
Maybe the odd treat just once a week but this'll soon stop as it'll make you feel relatively crap!
