I'm so glad you posted, Bodhi. This is a great place for encouragement & understanding. We all know the feelings you're speaking of.
3 days is a very big deal. I'm glad you have assistance from your GP. I spent so many years insisting I could manage the amounts I drank - I wanted more than anything to not let go of it. But why? In the end it was bringing me unbelievable pain and suffering. It tortures us. You can stay free of it, Bodhi. Congratulations for making this big decision to change your life.
