Jo,
I was invited to a neighborhood party after being sober for about 3 weeks. I really wanted to go and my husband wanted to go too. I didn't drink, but I had the most miserable time. I felt like climbing the walls and I hated that everyone was drinking and enjoying themselves. I went home sober, got up the next morning and went out and bought alcohol. So...like you, I learned that I needed to stay away from situations like that.
