Can relate to that, spent 5 weeks at Everest base camp in 2002 every morning when I woke up if you shook the tent you got sprayed with ice
Worst night was -31C, had 2 sleeping bags (3 season and 4 season) and all my clothes on to stay warm those nights and the morning after the prayers to Chomolungma by the Dali Lama to allow the climbers on to the Mountain, to much Chang (local brewed beer) at the party after. Jesus what a head from altitude and beer
