I frantically pawed through the cupboards looking for Lysol, cologne, hair spray, anything! The only thing I could find... a can of Lemon Pledge. I have always wondered what the next user of that bathroom must have thought. "Someone decided to do some dusting in here...?"
Oh, the stories I could tell! Staying at friends' houses or visiting relatives and cursing them silently for not having any sort of bathroom spray! I get mad, like, you're human, right? Where are you hiding your spray? Why are you hiding it from me? You think your stuff don't stink???
I keep a strong-smelling hand sanitizer with me and squeeze it generously to try and help the... aura of the area I'm using.
Sherry, as to your problem:
I wish you the best. Does your son shower at a specific time each day or does it vary? If it varies, maybe he can start a routine so at least you know when the bathroom will be being used and possibly avoid it, if possible. I do you your family cooperates for you, and good to hear it's only temporary.
