I'm going away with friend soon. She snores, loudly. The last time we went away I hardly got any sleep. I could get my own room but then this would make it more expensive for her as she too would need to pay for own room. I plan to take antihistamine to make me sleepy but anyone have any other tips? Thought of a sleep headband with white noise that I saw on Amazon - do they work? Any help would be appreciated.
