Hi Jeans. Welcome to the forum. There are usually two surefire signs that a person has a problem with alcohol (according to the Big Book): either they try to quit and are unable to; and/or they start drinking and find that they aren't able to stop. Hiding booze is usually a red flag too. In my opinion, it's not really that important whether or not you label yourself as an "alcoholic" or "problem drinker" or whatever; if you feel that you need help and support, this is a good place to find it. Keep coming back.
