Nobody knows that I have been drinking alcohol like a mineral water

I hit to the pub, to drink. Only to find myself tipsy... and drunk. It has become a habit now. A habit where people around me do not know or taken noticed of. I hide it from family and friends as our religious has restricted us from touching alcohol. For each and every time I drink, it reminded me of..... the 44 days unforgivable from god. I don't know how to stop. Nobody knows that I have been drinking alcohol like a mineral water. It's funny, I know....
