general anaesthetics - any tips how to minimise side effects?

[nightcat]

My son needs to have a mole taken out and because it's near the eye, he will need general anaesthetics.
I have heard that sometimes the after effects can be aggression, vomitting, sleepiness - does anyone know of any remedies to speed up the recovery process in terms of detox?

LOTS of water, IME.

i've always told the anaesthetist that i suffer from bad motion sickness - very true - and have been given something to minimise the vomitting and nausea.

thank you expat, good advice
(I remember vomitting myself after my appendix)
