Hi Reno, blackoutgirl is right. Try not to focus on what others are thinking, but rather how this is affecting you. One of the biggest reliefs to me was not having that burden of wondering 'what if' each day I was at work and drank too much too late the night before...
Now, if I'm running late, or something goes wrong in my day, I don't have that panicked feeling / paranoia that somebody knows I have a drinking problem.
It starts to make life so much easier when you begin to live honestly. And it starts with the first step of being honest with yourself. Things will get worse, I guarantee it. Freaking yourself out each day is no way to live.
