Feeling good can be a trigger for me too. Its like I feel good and just want to feel even better. And I forget of course all the misery that alcohol has caused me in the past. As someone said here, I must play to tape to the end the next time I feel that drink is an option.
That and stress are my triggers. At least I'm starting to recognise them now. Day 19 alcohol free for me and I am feeling much better. SR is an awesome resource !
