Welcome kpk; I know it's hard to admit to others you're struggling with this - and even harder to admit it to yourself. Sounds like you're on the right track. There's some good support here, look around, read and respond. I am your age, 38, went through treatment almost a year ago. Two bottles of wine per night was normal for me, though I would drink just about anything - it was vodka that nearly killed me in the end, you can read my blog post for details if you're interested.
Admitting you're seeking change is a big first step, but it's no picnic and it's not easy. There are some really strong addictions that are extremely hard to break. Do you have any plans to stop? Posting here is great - start reading around and find people in similar situations, you really do have to take hour-by-hour steps with this in the beginning.
Good luck!
