I was surprised when I saw there's a forum for flouroquinolone syndrome, but then the more I think about it, the less I'm surprised. I took ONE dose of Cipro in 1993. Within just a few hours I was completely psychotic and it lasted for 8 or 10 hours! What a nightmare. The bottle of those freaking pills cost $100 and they were total poison. I've since read that sensitivity to flouroquinolones can be genetic, so I've warned my other family members never to take an Antibiotic w/o calling me first.
