supplements for deep sleep

Hi

I need supplements that help me sleep (not nesseserily improve quality of sleep).

I've always been a light sleeper and every noise tends to wake me.
The problem is that I'm going on a 3 week trip with some guys. We'll share a large room and 3 weeks is too long to go without quality sleep. Probably some of them are loud snorers and I need something to help me sleep (I doubt earbuds will suffice as the sound of snoring, even if low, irritates me).

Can anyone recommend something good in my situation?
Thanks
