You honestly don’t need a lot at all.
I took –
– Spare knickers
– Macom bra
– Wore joggers, hoody and sliders on the way to wear back too
– Hair tie with no metal
– Cushion to put between you and the seatbelt afterwards (to leave in car)
– Bottles of water (perhaps just me but I thought the water at fitzroy tasted gross!)
– Sucking sweets or throat sweets, the anaesthetic gives you the most dry sore throat.
– Instant ice pack for the drive home (obvs a gel one would be melted)
That is it to honest! A face mist might be good too, to help you feel a bit fresher post surgery especially in this heat, but only if you have one anyways as you probably won’t care by then lol. Hope that helps!
