lol - yes, I simply may not have been paying attention, but I haven't seen anybody else talk about hiccups linked to benzodiazepene use.
HOWEVER, I definately had hiccups from Xanax (or, rather, alprazolam - the generic)! I typically rarely get hiccups, but on Xanax I would get hiccups several times a day. Sometimes it would just be one hiccup and that would be it. It wasn't unpleasant, and I would laugh nearly everytime I'd just have one hiccup.
It's interesting because one of the going ideas is that people get hiccups when they're nervous, but the xanax chilled me out (...somewhat, clonazepam worked WAY better).
I don't remember if clonazepam gave me the hiccups too.
