"I have not tried marijuana, but I am worried that it might make me more nauseated or vomit. Anything you can suggest to prevent this? "
Cannabis is a highly effective anti-emetic, meaning it prevents or relieves nausea and vomiting and is often used to treat nausea associated with migraines, inflammatory bowel disease, and chemotherapy. Start with a THC dose of 2.5mg and increase gradually if needed. Consider vaporizing, as this will get the medicine into your system within seconds and working to combat both nausea and migraine headache pain within a couple of minutes.
