I cannot say I ever drank when I was in work however I drank heavily after work each night.
i would wake up feeling awful with terrible anxiety I would drag myself to work looking pasty and pale. I found concentrating hell, I couldn’t eat and suffered terrible heartburn. I would start feeling better around 5pm and all I could think of was buying booze when I got home.
in the end I had to call in at least once a week because I was too hungover to function.
I am now sober for 4 months. I never want the above to happen to me or anyone else ever again.
