I don't sleep well the first few nights out but that happens wherever I might go, not just when I'm outside camping or backpacking. I start sleeping like a baby if I'm out for more than three days, but it's not often I'm out longer than that.

The people I backpack with I wouldn't worry about taking something. I wouldn't even think about it unless they said something like they were using it to fend off the cold. That would concern me and might keep me up at night thinking I need to check on them.

On the other hand, I have been around more than a few happy campers who drank enough alcohol to knock themselves out and ended up sleeping outside during some pretty cold nights and they all woke up, so maybe they're on to something crazy

"You want to go where?"
