Velveeta cheese shell cup from an 8 pack box. The kind you add water to then microwave then stir in the cheese part., 2 got sick. My hub had said he threw up and was ill. But he didnt tell me what he thought it was. ( hes had a prior stroke) so I dismissed it. I came home from work felt fine no issues of any kind. I made one of the cups since the box was open. I laid down and woke up 3.5 hours later with severe vertigo and nausea. I hobbled miserably as moving caused more nausea. Made it to the Restroom in time to toss back the cheese and shells. After purging my system ( throwing up) I felt some relief and hobbled back to bed. Woke up 3 hrs later and still having some slight dizziness but absolutely not like prioir event. Had I been able to leave my husband I would have called 911 for transport- it was that bad. Eyes still sore/visual trigger. Getting of internet.
