Asking for my daughter who is in college in VA. I'm in HI. She just texted me that she can't sleep because her mouth keeps over watering. The research I came up with says she might be tired, stressed perhaps. She flew back to college on the 28th, partied for New Year's Eve, and is not in DC on a 3 day interview for a possible internship. What can she do to fall asleep, day 2 of the event begins in 5 hours.
