Actor - Trying to lose the last few pounds the few weeks before a show

Hello!
I’m a (21 F) Actor, who is basically playing a stripper in a play. I’ve lost like five pounds leading up to this show, but i’d like to see how much i can debloat / lose a pound or two more in two weeks before opening.
this is not meant to be permanent, i understand this isn’t super healthy but id like to feel really good about the way i look in this role.
Other than cutting out sugar, gluten, and dairy - which i’ve been doing my best at doing, what’s the best tips you have for losing some water weight in a short period of time?
