I just ate lunch an hour and a half ago. I ate 1 chicken and avocadoburrito from there. Was nauseous after eating and just vomited. as I was finishing the burrito I started feeling very full, I only had 1 burrito. With in minutes I felt a bit nauseous and pressure in my tummy. After an hour past I vomited. I have had diarrhea for days now so thats not new but the stomach pain and nausea and vomiting are new.
