I stopped by DQ at about 3:30 and got a chocolate blizzard. At about 6 or 6:30pm I got diarrhea, within a half hour I started vomiting over and over then I got severe cramping in my stomach. All these symptoms continued until about 10:00pm. Then I just laid in bed feeling sick for the rest of the night. I started getting severe leg cramps at about midnight. These came for several hours. The next morning I was feeling better but still a bit queesy.
