I hid how much I drank, too. Turns out most everyone knew anyway. It's hard to disguise a hangover at work or among others. I got so tired of it. I drank so much more than others.
I lied and lied to others and to myself. Even though I knew I had a serious problem.
It would take me years to find sobriety. I really hope you don't have to go through the horrors I did. There is hope.
