Coping strategy:
don't do too much at once - that took me years to fathom

Graze - bananas, dried fruits and nuts, cream crackers, Rich Tea, ginger biscuits, Dextrose tablets
Graze before the body is hungry to avoid that awful nausea surge - took me years to remember that too

Sip tea
Pancakes are easy to digest
Fresh chicken diced with ginger, fried gently in olive oil and mixed with rice. Easy to pick at and to digest
Chicken soup is easy to digest. At my worst I would boil the kettle and pour over an Oxo cube, then I would take hours to even begin to sip it ......... as I began to improve I added boiled rice to the mug ......... it was Hard Work

but I did survive
The thing is not to forget to eat when we feel better! Catching up on sleep on a wet day is GREAT
