You said you were a "heavy dependent drinker" before you got sober. And now you say after your life is more stable, you're going to drink again!!!

Don't you know that you're going to end up JUST LIKE YOU WERE OR WORSE??? Can't you see that? So how can you question whether or not you're an alcoholic, if you were a "heavy dependent drinker" before and had to go to rehab?
When you "go back out for further investigation" it WILL get worse. You can bet on that. Plus, your liver isn't going to like it and will begin to show damage at some point. Alcohol DOES kill the liver. And you cannot live without a liver. Did you know that they do not do liver transplants on alcoholics?
I can't stress enough that you should NOT ever drink again, after what you've been through but that's your decision.
Congrats on 10 months sober.
