Food poisoning: The last thing you ate is'nt the cause.
We've all been there: you wake up feeling a little green around the gills, and before you know it, you're holed up in the bathroom for days. As you sip Gatorade and munch on saltine crackers in the brief respites from your body's need to evacuate its contents, you wonder, "What the heck did I eat?" While it's natural to assume that last night's fancy dinner is to blame (why did I have to order the mussels?!), chances are, you have to look back further than that. Food poisoning takes time, and it rarely sets in fast enough to come from the last thing you ate.
