promethazine is huge at the mmt clinics in my area. people pay upwards of $3 a pill for the 50mg tabs! I don't find it that helpful in potentiating the methadone, but that's just me...
I've been taking them almost everyday since elementary because of my allergies and also I have cats even though I'm allergic lmao.... no I do not find them recreational
Well I've used them daily for over half my life, have an almost pathological dislike of sobriety and can even find a niche in my neurochemistry for non-starters like Pseduo to retain some value, and yet even I think the first-gen ACEi's are as recreational as Typhoid Fever.
I don't take diphenhydramine recreationally to get high but I do enjoy they way it makes me feel when I take it once a week a before going to bed. While coming down from kratom it's really nice and brings a lot of the nice feelings back. I am a fan of diphenhydramine.
