> ...but he also thought a big part was camping at altitude for several days beforehand - kinda give me a chance to settle down instead of driving 4 hours from LA and then thinking I could go right to sleep.

And that is exactly why I take sleep aids when I go camping. There is no way I can sleep in a mummy bag the first night and get a solid sleep. It's not just the excitement of the driving and the trip, but the completely different environment. I wake up a bunch of times!

K.H, you could just try the Benadryl/Diphenhydramine at home to see how it affects you. It is an otc (over-the-counter) antihistamine or sleep aid. Like saltydog says, it comes in Tylenol PM, or you can get it by itself as a cold/allergy medication.

The one side-effect I noted last trip was that in the morning, my sinuses seemed exceptionally clear. grin
