Did you know that antihistamines are deliriants? My seasonal allergies were acting up one day, so I took some over-the-counter Loratadine (Rite Aid's antihistamine knock-off of Claritin). No hallucinations, no rabbits with pocket watches, but, thanks to cable news, I did see a square watermelon and a three-armed baby on TV.
