I spoke to my husband last night and he agreed to make the trip alcohol free. I can't tell you how much of a relief I felt about that. He's also agreed to abstain from alcohol altogether - and it was his idea, I didn't ask that he join me in trying to quit. He has about the same reasons/thoughts that I do about it at this time and I think it's the first time we've been in the same emotional place about it so I have hope.
So, hopefully we'll do well all around, and at least the temptation on the camping trip will be gone! There will be no one else with us who would be drinking. We've made plans together for fun things to do with the kids, planned a scavenger hunt and other things we can do together!
I'll let you know how it goes and thanks for all the wonderful advice and suggestions!
