The last time I OD'd(it was not on purpose), was in December when I was extremely sick. According to my body, I was not allowed to sit, lean back, or lay down, otherwise a coughing fit from hell would start. The only way to keep from coughing so much was by standing, and for nearly 48 hours I stood on my feet.
Medication was not touching this, and all I wanted was a few hours of sleep. And here is where I screwed up...
I ended up chugging about a half bottle of NyQuil PM at one time, way more than the recommended dosage. I finally dozed off... I don't think I dozed very long before the coughing hit again. In my mind, I had slept for several hours, when I reality, it was maybe 10 minutes.
So, I figured the NyQuil wasn't doing shit, so I downed nearly a half a bottle of liquid Mucinex.
20 minutes later, I was in an entirely new world. Nothing was right. I felt like I was floating. I heard music in my head and was actually kind of dancing to it. I remember it being a dark place. For several hours I was in this trance, and then I was finally able to pass out for several hours.
When I woke up, I looked up taking NyQuil and Mucinex at nearly the same time. I realized at that point, I was having lucid dreams. Although my mind was asleep, my body wasn't.
It may have put me in a different world at the time, but I do not want to experience that again.
