Here's a good way of testing if you're at risk of becoming dependent on alcohol: don't drink alcohol for an entire week. If you notice that you feel very stressed and need to drink alcohol in order to feel normal (not just the standard relaxed/inebriated), then that is a sign that you are at risk of developing an alcohol dependency. On the other hand, if you feel totally normal and have no compulsion one way or another, then you're fine.
