DXM, but you may throw up. Have an apt vomit receptacle ready, maybe next to your bed on the floor as you wait for it to hit. I always throw up with the 30 mg pills, but I am a small teenage girl so results may vary. Also, from experience, dont do DXM more than every 2 weeks. Once a month seems most optimal to me. You may experience an intense multi day migraine, that can come from abusing Analgesic (pain relieving) drugs. I did DXM (~225 mg each time) about 5 times in a 2 week period, and I had a debilitating migraine for 3 days, I am now completely fine. But the trip is great, I have yet to have a bad experience in the 20+ times ive used this drug. You can find the 15 mg pills at most dollar stores, and more potent forms online. OH ALSO, visit https://dxm.tripsit.me/ for a dosage based on your body weight. If you feel particularly adventurous, try mid 2nd plat for your first time. Have a good time!
