Family man...I've been exactly where you are now, high tolerance, drinking every day, suspecting I was an alcoholic etc. I woke up ever morning and swore it off, and found myself drinking every night and never suffered much from hangovers. This merry-go-round went on for years, as a result, my family suffered, I lost jobs, and ended up with dui's. The fact is, if you think you have a problem with alcohol, you probably do.
You don't have to hit bottom to stop drinking... you can get off the elevator at anytime.

AA is a good place to start. You will find wonderful,friendly, supoortive, people who can totally relate to you. AA is a spiritually oriented program, and recovery is an "inside Job". If this doesn't work out for you, there are other alternatives.
Please seek help today, pick up that phone, my friend. and dial
the AA hot line number. Someone most likely direct you to the closest meeting, or take you there personally.

I wish luck and success, it's not easy crawling out of the bottle, but it is doable.
