When I have a 'big event' (family party, evening outing, etc) I do nothing the day before, really light stuff 2 days before and block out my calendar the following day. This got me to and recovered from a Rolling Stones concert & a professional hockey game!!! Both had tons of auditory & visual stimulation, along with what I now know is 'complicated' brain work-getting to an unfamiliar place, finding the right entrance, finding my seats and a bathroom. Basically , an 'event' costs 3 days-it helps me choose what is worth that.
