Black grapes I ate an handful of grapes, started feeling nausea shortly after consuming, certainly within a couple of hours, if not sooner. I vomited within 3 hours. I ate the grapes again, not knowing it was the grapes that caused the nausea and vomiting. I ate a lunch sized portion around 1pm. That was all I had for break and lunch. I began feeling nausea within the hour and vomiting occurred the first time at 4:07pm. It continued throughout the entire night. The last vomiting occurred at 1:38am, however, the nausea continued into the wee mornings. I couldn’t hold any fluids down, and I was vomiting continuously. Could not participate in any activity during this time. I experienced dizziness, headaches and lightheadedness. I had no control of the vomiting, I vomited on myself and in my shower when I was trying to rinse off. I tried ginger and lemon tea, that also came up. I am extremely dehydrated and weak and it has been 25 hours since I last had the grapes.
