While sobering up in a less-than-luxury treatment facility (which I did need), I was put on a number of psychiatric drugs. Principally, these were Neurontin, Serzone and some Klonopin. Klonopin was less than 2 mg daily, but I don't recall the Serzone dosage. But the moral of this story is as follows:
My mind had been reasonably messed up on a combination of alchohol, club drugs and undiagnosed psychiatric conditions. Neurontin was prescribed early on, but as my insurance was dubious, I was getting sample packs of neurontin from the psychitrist (when outpatient). I started with lowers dose (400 mg x 3 daily) and increased. Eventually, I was prescribed 1,000 mg x 3/day. That's a lot, I am told.
Now I've mentioned that my mind was messed up generally, and one of the things that I had to do was compile dosages from the various samples to get up to the 1,000 mg mark (he had no 1,000 mg samples). Simple, but not for me. Somehow I got really confused and was taking 3,000 mg three times per day (9,000 mg). This lasted several days.
During this period, some of the things that happened are as follows: (1) I stopped at a stop sign and waited for it to change (unlike stop lights, the signs don't change); (2) it was impossible for me to distinquish between the hot and cold water knobs while showering, except by experimentation (ouch!); and (3) the difference between the 'up' and 'down' buttons on an elevator essentially went away, resulting in necessary trial and error. I only did this for a few days before I figured out what was going on and stopped. It was close to a disassociative effect, but generally falls into that broad category of 'zoned out.'
I'm told I didn't hit the record at 9,000 mg, but I'd sure want some fairly sober people around me before doing that again. I might decide that the best way to get a bottle cap out of the disposal when I couldn't quite reach it would be to turn on the disposal for a 'second or two.'
