Hi Danemum,
I've only ever had it once under a general. That part was fine but I didn't feel crash hot after I woke up- giddy and nauseas. At worst though I'd describe it as unpleasant.
Having said that- I'd been under a general three times before with other procedures and had no after efects then. So I just got unlucky this time.
Given the choice I'd probably ask for local and light sedation next time.
