anesthesia
"I had to have injections at cervical levels 1-2 & 3-4, they call this drug twilight. I loved it!!! My anesthesiologist said I would feel a burning in the IV of my hand. I felt nothing. It took me about 10 secs to fall asleep. I woke up with oxygen and was ready to go. I was driving about 5 hours later. Walked right after procedure and had the best nap of my life!!! The only thing is and I not sure if it is the twilight or the meds injected in my neck but I cannot go to sleep now. I have a ton of mental energy. My procedure was done at 12:30 pm and it's 4:30 am and I'm wide awake."
