I have been playing with DXM for a few months, usually by boiling the proper DXM-only cough drops until the powder is freed and pouring away the gunk. It's made him sick several times, and he's come to believe the "dirty" feeling that some ascribe to DXM is nothing more than the dissociated mind's way of communicating nausea. He thinks this often gets misinterpreted as horror, leading to bad trips. He has thrown up even after taking two precautionary dimenhydrinate pills before the trip. He thinks he's finally found the Right Way to do it, however. Forget the syrups. Get some DXM HBr powder and mix it into some 180 proof ethanol (Everclear) at a concentration of 50mg/mL. You'll only need to down one swallow instead of chugging a vile glass of aqueous solution. Finally, the magic step: add 1/4 tsp of citric acid to your dose. The last part came from a hunch. I'm still not sure I understand why it works - the Internet tells me that most hydrobromide salts are acidic, so the citric acid shouldn't have help. DXM HBr tastes bitter as hell to creatures, however, so maybe it is basic after all. Maybe adding citric acid raises the pH to a level more acceptable to one's stomach. I haven't witnessed any sort of acid/base reaction like one gets when mixing citric acid and baking soda, though...it just sits there. SWIM starts with an empty stomach. He takes 50mg diphenhydramine HCL (Benadryl), wait twenty minutes or so, and then down the DXM/Ethanol/Citric Acid concoction in one gulp. The result is all the benefits of a DXM trip with none of the drawbacks. My knowledge of chemistry is limited. Perhaps someone more experienced could shed more light on this.
