So last night I took 100mg of tram, my normal dose, on an empty stomach as always. I felt good for awhile, about 6 hours, when all of a sudden I got terrible nausea and just vomited for the rest of the night even though I hadn't eaten. I puked from 1am until 5am, when I finally forced myself into bed and slept for 12 hours. I felt fine when I awoke. So, my question would be, what the fuck? I've never had such an adverse reaction to it. I didn't do anything different.
