Question: Last night at 9pm I ate eggs with cayenne, and took 500mg of an herbal supplement called "Cat's Claw" ( Uncaria tomentosa). I had a cold, so I took two Nyquil liquicaps; one at 9:30pm and the other at 10:00pm. This is the recommended dosage. I went to bed at 10:30pm.

My dreams were very vivid.

At around what I believe to be 6am I began having the sensation that something was vibrating in my head. I was half awake. I thought at first maybe my scalp was twitching, but when I placed my hand on my scalp I did not feel anything twitching. I also felt my heart beating rapidly, but when I placed my hand on my chest I did not feel anything abnormal. I also had an image in my mind of something turning on and off, like something was being reset. I wondered if I was having a seizure (which I have never had before). So, I asked out loud, “Am I having a seizure?” to determine if my speech was slurred. It was not. I went back to sleep.

My alarm went off at 7:30am. I got up and began to walk to the bathroom, but I felt very strange. I did not want to be standing, so I sat on the floor. I felt as though my brain was working too hard trying to make me stand. I started praying, and felt a little better.

To test my brain’s ability to function I stood with one leg on a balance board and tossed a bean bag from hand to hand. I was able to perform this task without difficulty.

For the next hour I only felt concerned, maybe a little afraid.

Around 9:00am I heard a buzzing sound. I walked around the house but could no isolate it; the loudness and pitch did not vary based on my location. I inferred that the sound was in my head.

Did I have a seizure? I am wondering if the cayenne and/or Cat's Claw interacted with the Nyquil.
