Hi Rennie
I can relate to your story in that I functioned like everyone else and most people would not have thought I had a massive drinking problem but like you I could not stop at one, two or three, occasionally it was possible but 95% of the time is wasn't. I came to the realisation that having nothing was the only way I was going to be able to control my behaviour and that's what I have done. It's worth it, I just tell people now I just don't like what alcohol does to me, I haven't came across someone that can argue with that!
Good luck
