anesthesia
"Had a colonoscopy with propofol. I went out quickly and didn't experience any problems during the exam. But afterwards,  in recovery I felt drowsy and unbalanced when asked to get up to get dressed. It seems like you are forced to leave recovery too fast. Finally, I was able to walk to the car. Once we arrived home I had severe nausea and I felt like vomiting.  I wasn't able to get out of the car. We called the doctor. He told me to stay reclined in the car and do not eat or drink anything. The good thing is I was in my garage away from the cold rain. After 2 hours I was able to go into the house. Called doctor back. He informed me I had a reaction to the "new drug" aka Propofol. Other effects:Chills, sleepy, tired. NEVER again!!!"
