hello tee.... welcome ..... well first of all i worked for NHS for over 8 years nursing and i have had a few ops in my time for this and that ..
general anesthetic is a doddle you have nothing to worry about there you feel nothing when going under apart from like your floating on a cloud and then your fast asleep and wont rem a thing...
then when they bring your around its just like a daze you wont be any pain cause they have filled you with enough pain killers to knock a horse out ...
you will daze in and out of sleep for a fair few hours and wont quite know where you are for first few hrs and you wont care lol .. happy place to be trust me ...
you will go to recovery while they are bringing you around and depending on what kinda surgery you have had they will rather send you to ICU .. or to your room ward .... where you will then sleep the best part of the day away and will wake now and then for short periods of time ..
if ur having bypass you will prob have a little press button for your pain killers that will give your morphine or the likes .. you press when you feel any pain and it all goes away ..
so i would no worry if i was you just think of the out come and all the good things you will be fine ..
and good luck keep us posted on your results ;o)
