The effects of sedation will begin to subside after about 30 minutes of you having your procedure. You should feel completely normal again after 24 hours. One of the (many!) fantastic things about sedation is there is generally no ‘hangover’ sensation, something that is closely associated with going under general anaesthetic.
Whilst you are awake for the duration of the time you are sedated, it’s completely normal to forget some of your procedures. This is due to the amnesic effects of the sedative.
