Try this: stay sober for 6 months. If, after those 6 months, you still really feel like you are missing something- the bars aren't going away, the liquor stores aren't going away. You can always go back to it.
But, why not try a life sober? Why not see what happens when you're in control of your nights out, when you don't feel hungover, when you don't blackout and regret your choices?
Try to find a local AA meeting. Helps me so much.
