One not mentioned on this page is dexchlorpheniramine. In my personal experience, exceeding the recommended dose and fighting the drowsiness effect leads to quite a pleasant high and mild aphrodisiac effect.
That’s kinda interesting. I’ve only ever heard of DPH and Doxylamine (which I’ll on occasion use as a terrible sleep aid). I knew other antihistamines exist, but was never curious about their effects.
