I think this is fairly normal in early recovery, and as someone else said they are just thoughts and they do pass. Its all part of the insanity of the illness, that mental obsession with alcohol 'oh wouldn't it be nice?!" Been there done that, I wound up drunk.
It does get easier. The one day a time thing helps for me whenever I feel like that. The achievement of getting through another day sober is immensely rewarding, I wouldn't swap that for guilt and regret, no way!
Alcohol is a poison to the alcoholic. There is nothing fun or nice about it. Keep that in mind x x x x
