Hi Paul, oh I wish I had have had your insight and strength to quit in my 20's, you've done brilliant!
I found a void living without drinking, although it's great being sober, I am learning to recover from it. The things I buried with drink are coming back clearer and I was advised not to do any life changing events until at least a year sober. Good advice, I have heeded.
Have you thought about having a chat with your doctor, it can't hurt and there may be some help/advice he can steer you to.
Well done again.
