Propofol
"I am a 32 year old male, and have been experiencing some pretty scary health issues. About 8 months ago my hair started falling out in random patches, and I have lost pounds in the same time. I was schedules for a colonoscopy and endoscopy. Yesterday I checked in for that. I am a super nervous person. Have been diagnosed with severe panic disorder caused by anxiety. I have always feared general anesthesia as I have some sleep apnea issues. Could not believe how quickly I went out and then was in the recover area with a juice box! No more worries about this drug again. Also had a runny nose and slight eye irritation.  It surprises me that none of you would know that its from the oxygen in your nose though? Obviously."
