3 Cups of Coffee Increases Hallucinations

PearsSoap writes "The Telegraph and other sources are pointing out a study on 200 students which has found that a high caffeine intake can cause visual and auditory hallucinations, and can make people think that others are 'out to get them.' The abstract (and full version if you have access) is available. 'The volunteers were questioned about their caffeine intake from products including coffee, tea, energy drinks, chocolate bars and caffeine tablets.'"

    Back in college, when I was still super driven to be the best at everything, I used to down several cups of coffee and tea at night in order to remain awake and focused while doing my homework. It got to the point where after drinking the tea, I would suck on the teabag (keep your wiseass comments to yourself, thanks) because I'd read that saliva could extract even more caffiene.

    This all ended one night when I woke up at about 3AM (after staying up until 1 doing some Physics III homework) with what sounded like a couple of dozen people having a rally in my head. I couldn't make out individual voices, words, or sentences, but the sound was distinct: lots of people were talking over one another, LOUDLY, and there was no way to get away from it or make it quieter. It was, frankly, extremely frightening, even though it only took a minute to realize what was going on and why. I wound up lying on a couch in the common area with a pillow over my head for about an hour, wishing the noise would stop so I could actually get some sleep. Eventually, it quieted enough that I could crawl back into bed and catch another four or so hours before needing to get up for class.

    Anyway, caffiene: it's a drug, and now I limit myself to one cup in the AM and occasionally another in the afternoon, or a very small cup with dessert. Auditory hallucinations are no fun, and I found that I value the quality of a healthy life much more than the rewards of intense focused work these days.

    On the tequila side, I went to a party with my wife back in 2003. I brought an entire bottle of 1800 Jose Cuervo and OJ as a chaster with me with the full intention of sharing it with many other party-goers. Unfortunately being that the party was on a Wednesday, they weren't quite as interested in drinking tequila shots as I was. I drank the entire bottle (minus three shots) and an entire bowl of Doritoes.

    The next part I am not proud of on any level but explains why people should not drink tequila:

    I don't remember anything until noon the next day when I awoke on the couch and said, "holy fuck I didn't go to work!" I called in to work to apologize. My coworker just laughed and laughed and laughed. Apparently I had been in that morning and was sent, by her, to Burger King to get a Whopper to sober up. It didn't help and it was suggested I go home.

    After getting off the phone with her I went to take a shower to find that the bed sheets were all in there covered in puke, causing me to throw up again all over them. After finally cleaning myself up I went and looked at the bare mattress, now stained bright orange from the Doritoes and decided never to drink tequila again.

    For the next week I had huge, itchy rashes all over my body. My doctor asked if I had been drinking heavily and I recounted parts of the above story.

I had maybe half a dozen cups of that, and my friend and I were having a ball talking about all sorts of wackiness. Once the diner kicked us out to close, we went driving on back country roads like usual to catch some air in some places and continue talking.
