Sometimes i don't even have to go to sleep cause in my country we open the gifts on Midnight and we've brought the tradition to the US with us lol but if we feel real patient then we wait till next morning then i fall asleep at like 3 or 4 lol
in my family we celeberate the 24th into the 25th, so we stay up drinking eating etc until midnight at which point we open presents! so i never have to worry about sleeping on christmas eve
