Its just not the same

I go on drinking bends every year and a half or so. But this time is different. As i come to the end of my time drinking due to weather i notice the liquor that was doing a damn good job the past few months is getting me drunk but suddenly Over the last 3 days its just not hitting the same. The music isnt interesting me anymore and the food i buy in preparation doesnt even sound good to me after i start drinking. The whole reason i drink is to enhance my regular actions but its suddenly stopped.
