Step 1: decide to never eat anything again.
Step 2: remember, with great relief, that you stored a bottle of Gatorade, after the baby was taken with Winter Vomiting Disease last winter, for just such an occasion.
Step 3: refrain from looking directly at all food inside refrigerator whilst retrieving the Gatorade that you will be drinking by the spoonful every couple hours.
Step 4: sleep until it is all over.
Step 5: realize that Step 4 is impossible (both because of incredible agony as well as the existence of baby-turned-toddler in the aforementioned Step 2).
Step 6: realize Step 1 is impossible as well, and instead venture into the world of soup broth and saltine crackers after 24 to 48 hours have passed.
Step 7: do not have a husband that also gets food poisoning at the same time.
Step 8: if you cannot achieve Step 7, than at least be thankful you moved out of that house with its single bathroom.
Step 9: with a hardened stomach and suspicious eye, throw out all food from the refrigerator. Especially that take-out box you got the night before.
And finally, Step 10: begin your illness on Christmas day so that available in-laws are on hand to chase down a healthy and energetic toddler who, while not able to identify the agony his parents are in, is keenly aware there are presents waiting to be opened.
