vegetariansalad-lentils, avocado, pickled carrot, spinach. Lemony dressing. I bought the salad around 4 pm. I had not eaten lunch. The nausea started when I got into bed, around 11:30. It got progressively strong and I could not sleep. I decided not to vomit, but could have easily. I looked up how to relieve nausea and found sutting up a fresh lemon and smelling it and sucking it did the trick. I did not have any fresh ginger, which is the preferred remedy. The smell relieve the nausea and I went to sleep.
