When i go to the dressing room I get the strangest urge to use the bathroom.
Really, is there something specific about dressing rooms?
I feel like half of me is being depleted.
You should use the bathroom when you get the urge to. You should use it before going into a dressing room.
You're probably right.
If it really becomes a problem, you should try going to the bathroom first when you know you have to visit a dressing room. That way it shouldn't be a problem at all.
