You are very unlikely to die from lack of sleep.
you have an extremely good chance of dying from drink, either directly or indirectly.
Rest assured that, however bad you think your drinking is now, it is almost certain to get worse within the year and to continue to do so. By worse, I mean that your control is likely to decrease (8 will become 7) but also that the consequences to your mental and physical health, dignity and life with others will be increasingly affected.
IT IS NOT GOING TO GET ANY BETTER THAN THIS.
The good news is that, if you have decided to do something about it, there is a solution, and your life can get unimaginably better in a comparatively short time. The worst of your days as a non-drinker will be better than the best of your days as a drunk.
There are a range of approaches to this solution, with or without AA, but most people would agree on the following as a basis for getting better.
Take it one day at a time - don't project or plan
Allow yourself to be helped by others who have been there - accept that you cannot beat this alone and that you are not all-powerful
If you fail, try again
If you succeed, try to be grateful
When you've had a couple of days free of the drink, start thinking about what is wrong in your life APART from the drink and what you personally can do to fix it
Be ready to help others who are even newer than you
focus on not drinking - don't beat yourself up on other "bad behaviours" like eating or smoking too much, you can fix that later
Keep a clear idea in your mind of what drinking is REALLY like, at least when you're involved
Most important of all, remember - you are not a bad person trying to get good, you are a sick person trying to get well
Happy to help in any way I can if you would like it.
Good luck.
