The first time that I had Versed was for a colonoscopy. I had been told by the doc. that I would be knocked out. I was told by the nurse that I would receive a twilight sedation. No one mentioned Versed or the amnesia effect of it. The Versed was administered in the procedure room. The next thing I remember I was back in the holding area where I started. I wanted to talk but found that my words couldn't catch up to my thoughts. I vaguely remembered saying ough during the procedure and wanted to ask the doc about it but couldn't get the words to come from my mind to my mouth. For the next several weeks, I had the strange feeling of trying to remember something that I couldn't. Like when you know that you know someone's name but you just can't remember it. It kept my up at night thinking about it. It was the first thing that I thought about when I got up in the morning. A strange obsession. I contacted my doctor's office to get a copy of the procedure report to find out what kind of drug they had given me. That's when I found out about the Versed. After researching it on the internet I found out about the amnesia effect. Then my weird feelings after the colonoscopy started to make sense. I vowed to never have the drug given to me again. I complained about it to everyone who would listen and no one could understand why I was upset. For months and months I obsessed about it. Then I found out that I had to have surgery. I had assumed that I would be under general anesthesia, which I was, but they gave me Versed before I was wheeled to the OR. I had no idea that they used Versed before gen. anesthesia. So I went through the same weird obsessive feelings for several more months. That was 10 months ago. I still feel as if I've been mentally robbed. I was so glad to find other people who have the same feeling about Versed that I do. I was beginning to feel as if I was alone. This stuff used to be used primarily in pediatrics since 1986. Now that adults are getting it, and complaining, I wonder how many kids had it but with negative affects but weren't capable of voicing their neg. experiences.
