I could relate to you post and no way is 38 too late. I was 39 and the thought of continuing drinking to oblivion every weekend into my 40s sounded more and more pathetic. I was sick and tires of being sick and tired. Always planning the next drink, being hungover, then in withdrawal. I only had one day a week where I felt back to "normal", then it was time to drink again and it started all over again. It's much much less exhausting living sober. It's the hardest think you will probably ever do, but life is so much better without it. Good luck.
