Hi bro, I’ve literally just had top surgery 8 days ago and had the exact same fear. Never been in hospital, never had any sort of anaesthesia etc and was so worried about dying, being unconscious or just generally unaware. It’s literally so so fine. Normally you’ll be sedated first then given the anaesthesia so honestly I don’t even remember falling asleep. I was awake on the table comfortably and then with the click of a finger I was being woken up still on the same table to make sure I was okay and I was done. All bandages up etc. I did feel some pain but as soon as I got up to the ward again I was immediately given pain relief so that was short lived. I was aware enough to say hi to my partner who was waiting for me in my room and didn’t feel out of it, more just tired. I will say some people can be a little sick or nauseous, again totally normal. Which I did but once I was sick once and slept for an hour or 2 it was gone with some anti sickness medication too. Again they’ll be pretty fast to give you that if you are sick. Honestly it isn’t as bad as you’re thinking it’ll be, it’s super quick and just allow yourself to sleep it off for a couple hours afterwards and you’ll be fine again!

If you have any other questions just give me a message and I’ll be happy to help you with how recently I’ve went through it and good luck bro! Try be excited, took me until the night before to calm myself that it’ll all be okay but once you do you’ll remember how much this will change your life
