Does my body recognize and reject DXM?

So I started robo tripping at the beginning of 2022 just before my 15th birthday (right?) and for a year after I consumed dxm pretty consistently. At least on a weekly basis sometimes daily. During this time I would throw up about 40% of the time about an hour after consuming (either robocough syrup or R30s freebase)

During my last couple months of consistent use I would puke without fail 100% of the time. This was the beginning of 2023. Spring 2023 I quit and didn’t have any again until August that year and again I would have the most miserable stomach pain and sweats and it felt like withdrawal. But once I puked I would feel fine.

Whether I would puke before the dxm hit was always the gamble.

After that I said I was done and would wait about another year before even thinking about it again. And I stuck true to my word.

Come October 2024 I am now 18 and I had gotten ankle surgery that put me OOC for a while. Thought it would be a good time to revisit my old friend.

Like clockwork I looked at them(r30s) , I would get a chill down my spine and almost throw up from the anxiety before I even ate them. I munched. 30 mins later I’m dying on my bathroom floor, I puke, I chill then I trip.

Obviously through my past use I built up a tolerance. I thought it would’ve stabilized in a year. But it felt dull and not fun like had my last few months of abusing.

Thanks for reading my experience:)
