Do Nasle Snoring Strips really work?

I'm attending a wedding soon and flying for about 12 hours. I don't want to be the burden of other people's travel, nor do I want to be the only one stuck with half the family in one hotel room where the bride and groom forgot to mention our stay was across town. Nearly 20 people (I kid you not) squeezed into a two bed suite, on the floor, couches and about 6 people each facing head-to-toe on the two separate twin size beds. The only problem is, I snore quite a bit, and since I'm a really deep sleeper I've been told car toys and light bulbs thrown at won't wake me up. I need help fast. Any suggestions?
