light anesthesia
"I recieved medazilam, commonly called versed for my first colonoscopies, note versed is a amnesia drug they use so you "forget" how bad they treat you, and that you were in pain rather than relieve the trauma. I suffered anxiety,  long term amnesia, flashbacks and a PTSD-type reaction to the use of this drug. Not only did i loose the abity to lay down memory properly long term but the patches (it kinda feels like the connections are there of the bad experience you feel the trauma but you cant pin it on an exact block of memory) of the trauma remains i highly recomend the non-amnesic fentanyl instead for colonoscopies."
