i have totally been there. it slowly went from drinking occasionally at lunch to everyday. coming back buzzed and being able to pull it off for quite some time. clients and other employees began to notice and word quickly spread to my boss. i was immediately terminated. after four years it all came to a grinding stop. it was a wake up call for sure. i went to rehab shortly after needless to say. but i lost alot. you still have your job. drinking during the middle of the day was something i never thought id do. or need. but it quickly became a pattern. looking back it wasnt worth it. people are definitely watching. and if they even suspect it they will be keeping a close eye on you. believe me. try and change your routine. i know its not easy. much luck.
