Hey good on you for hopping right back on the wagon, remember though, the more often you fail, the harder it's gonna be to stop because your will power takes a beat beating each time you relapse, so put forth major attempt in trying to make it stick.
Always remind yourself, if you haven't drank in a very long time, chances are is that booze will only make you feel tired, and sluggish because the alcohol is very foreign to your body due to your sobriety.
