I took Klonopin (clonazepam) once, per doctor. I couldn't remember what happened exactly (all the hours after I took 1 mg). The next day my anxiety was off the charts but after some investigating (asking people in my family) I didn't do anything out of the ordinary and watched TV. But the "not remembering what you did" is too high of a price. This scared me more that the day-to-day anxiety. I told him Valium (diazepam) does the job better w/o being ultra-anxious because I couldn't remember anything. This was in 1998 when I had premium insurance and it was a "new". I'll never take clonazolam again, somehow clonazolam works pretty good, but it has a pretty high sleepiness effect
