Welcome to SR. I to have been sober many times and relapsed many times. Man I tell you this is a hard road.
I am again 27 days sober. This weekend I had a horrible time, It was 85 degrees outside and a beautiful day, and we had a BBQ. I made it and am happy I did. You can do it, dont be hard on yourself we all make mistakes hang in there.
You know what helps me is knowing, I will not wake up crapping my brains out, and my kids looking at me thinking you look like crap dad. I had horrible stomach problems when I drank, and now my stomach is about 80% better. Thats worth it to me.
