I drank nightly, but my nights would often start by 2 pm. I'd try to "dry out" for 30 days or so once a year, often to coincide with Lent. Often, I didn't make the whole stretch. But I did "quit" and get 60 or 90 days one or two years. I also quit for 9 months when the wife was preg with #1, and for most of her next pregnancy. These patterns continued for about 30 yrs. The first 10 included daily pot, occasionally any other drug that didn't have to be injected. Then, drugs gradually tapered away, and in recent years were replaced with prescription narcotics, which I've also now quit.
Amazing thing is that my life always improved dramatically when I quit, so I figured I was cured to start over. This time, God knows better, and gives me gradual increments of improvement, and I've strung together 8 months, with no "end date" planned or in sight. Thanks to God, SR, and AA, my life is getting better every day.
