Welcome Jeans.
You don't need to figure out if you're an alcoholic...first you need to realize you are having a problem with the booze. You don't have to be an alcoholic to feel as though booze has left you unmanagable. But typically, that's a good indication.
I knew I had a problem long before I came to the thought of ever being an alcoholic. For some just the word alcoholic is scary and no one wants to admit to that.
If you have to hide the drinking and feel you are drinking too much then you may want to re-elvaluate your relationship with it. One step at a time...one day at a time...
