I had that twice. it's called toxic psychosis in the package insert. I was unable to even call 911. Just laid there for 24 hours having what I imagine was something akin to a very bad LSD trip. Took weeks to get over it. Of course my doctor said it was just some mystery illness unrelated to the drug. Four yrs later had the same reaction from eating a piece of chicken back when they used Baytril, a vetrinary version of quinolones, in poultry. It has since been banned for use in poultry. As far as I know they still use it in non-bird food animals so I don't eat them unless they're organic.
I was in my 40's then. I am 62 now. I would not expect to survive another exposure.
