I'm actually passing on a camping trip with friends coming up for the fact that I worry I'm not ready to handle all the drinking that will be going on. Besides just being around it and, I'm sure, wanting to drink out of habit t least, im worried about having no exit strategy if the temptation really hits (they are going 3 hours from home, a little harder to just up and leave then say a local friends house). So im happy to hear you are doing well on your trip!
Instead of going with my friends, my husband and I are going to go by ourselves soon, which I'm hoping will be a nice dry run (haha) of getting used to camping sans booze. I'm really looking forward to it since I'll actually get to enjoy hiking and stuff instead of just "getting through it" with a hangover, counting down the minutes until it's time to just sit around the fire and drink again.
Cheers to you and many more sober camping trips for all us nature lovers!
