Lavallette, welcome and well met. I'm glad that you have found us here for the reason that your presence and your addition to the team has already made a difference to someone, stumbling on your post, who is just now understanding that they can indeed quit drinking.
For me, facing the 'loss of that wrongful pleasure' has meant that I have accepted the possibility that I can succeed, that I can have confidence in myself, that I can have a life that gives me self respect, and my own measure of joy and beauty in my life. That possibility is realized through my demand that I will accept nothing less, and that I will succeed.
Best to you.
