as much as you want
Я прикажу купить тебе таких сколько захочешь.
I'll order as many of those for you as you want.
— Подними красный фонарь (1991)
I'll give you as much as you want.
Если тебе удобно на диване, то можешь оставаться здесь сколько захочешь.
If you're comfortable on the couch, you can stay here as long as you like.
— Суспирия (1977)
