It was kind of crazy vomiting up to twenty times a day. It was hard to make the connection at first because I wasn't a heavy smoker upon my return. I feel as though something shifted in my body chemistry after being a heavy smoker for so long and then quitting for five and half years. It was hard to find peer-reviewed articles at first as all thing pointed to Cyclical Vomiting Syndrome. The other thing that made research was the war between naturopathy and western medicine. The biggest lesson I learned was to be very mindful of what you put into your body. I think marijuana is a very positive thing that deserves recognized and studied.
