Missy,

The natural herb I use to help with sleep is valerian root. It's totally natural, and I haven't heard of any bad side effects or interactions (except not to drink or operate machinery when using it!). I recently started using NOW brand liquid valerian root extract, and it helps tremendously. I've been super stressed out lately from going back to school, starting a new job, etc....so I have had heart palpitations and major problems in getting to sleep. The valerian root does knock me out though, only it takes about 45 minutes to kick in. It's super cheap too.

I hope your flight goes well. It can be problematic taking supplements on flights, and that was before the latest security increase. I didn't want my x-rayed either, so they had to individually test them to make sure they weren't hazardus - it was quick, but they of course argued with me about the necessity. Just make sure everything is in it's original bottle, or else they can give you a hard time or throw it out. You might want to call the airline you will be flying with to find out about their policies on vitamins/supplements - that's what I did before I flew last. And on the plane, maybe you can ask for extra water or something, so they no longer allow it to be brought.

Good luck and have fun on your trip!
