anesthesia
"Upper endoscopy with propofol. I'm prone to panic attacks and nervous around drugs. But I can see now why some people call propofol a miracle drug. I had a mild burning sensation in my arm as it was injected, like a slight bee sting, lasted 10 seconds. I don't remember falling asleep, but it must have been 20 seconds or less. I had no memory of the procedure, nor any discomfort. I woke up in a new room what felt like an instant later. Mild after effects: drowsy, loopy/euphoric (everything seemed funny), my limbs were heavy and I was a bit unsteady. But I was mentally alert, able to start eating, dressing, and using my phone to type emails within minutes of waking. Easy, easy procedure, so if you're an anxious type like me, don't worry."
