I accidentally posted this on /dis/ so I'm reposting it here. I have had some severe vertigo after a head injury a few months ago and the stupid GP gave me a bottle of meclizine and even lied to my face saying it would cure me. I finally got to see an ENT specialist and she told me not to take it anymore and just start physical therapy in a couple weeks. So now I have this bottle of meclizine and I am wondering if I can trip on this stuff? I hear it's very similar to DPH chemically but all the erowid reports I can find either say that nothing interesting happened, or they took it with some other drug that I currently don't have and don't feel like acquiring. So how much should I take? I'm 6'0", 200 lbs. What kind of dosage will make something interesting happen?
