Scopolamine
"I put the patch on the night before a planned mountain excursion.  The morning I woke up, my vision was extremely blurry (couldn't read), I had severely compromised mobility (stumbling and tripping), decreased ability to comprehend what was being said to me, as well as very dry mouth. I also began hallucinating, so I took the patch off.  Within 1 hour I started to feel a little more in control, and after 10 hours the side effects seemed to be gone.  
I had the patch on for a total of 8 hours, and felt like the patch was WAY too strong - to the point of overdose.  I made sure to wash my hands after putting on the patch.
I also take ortho-tri cyclin lo, propranolol 60mg for migraines, and Zyrtec."
