It is possible to bring the bottom up to hit you. it just requires you to be honest with yourself. It seems from your post that the problem is getting worse. Also, when you start, you can't stop. That means you have the phenomenon of craving which never occurs in the average temperate drinker. So you have ticked two boxes, progression and craving. The question now is whether you can stop on your own power.
Darkdays makes a useful suggestion, just stop. If you don't take the first drink, you can't lose control. It's worth a try, it works with many if not most problem drinkers.
If that doesn't work it means you have lost the power of choice, and this is where the bottom can hit you. To realise that you are actually dying of a progressive illness which, unless arrested, will lead to insanity and death can be a great motivator to get help.
It would require all the honesty you can mjuster to recognise and accept this truth, but many do just that these days and have great recoveries. There is nothing that says you have to descend to the pits that some of us have before you can get well.
