I saw demons and had similar night terrors while on Vicodin. Totally terrifying.
It's the only pill I ever flushed down the toliet willingly and with relief. I always say, "Satanic" when describing Vicodin.
The ativan is a Benzo as you know, it's also dangerous but my bet would be squarely on the Vicodin.
Eagle you're cracking me up!
