Hi! I have been put under 9 times. 8 of those were for surgeries. I can answer the what does it feel like question...you just go to sleep, and NOTHING! It happens fast too. I did wake up during my last surgery. I was bleeding out from a rip in a blood vessel from a surgery 3 days earlier, and during the repair surgery I woke up to find hard tubes down my throat, but not long enough to feel pain. As soon as the staff realized I woke up, Boom back asleep! Not the best memory in the world but not the worst either, just different. I also probably woke up enough to hear the surgeon on another surgery, cause I "knew" just how long it took before they even told me after surgery. Or I died momentarily and then came back. Either way, it was not scary.
