I could've written your post. I was waking up every morning with shame and regret. Every day I told myself I wouldn't drink. Every night I'd drink again.
I haven't had a drink in 28 months. Life is much much easier without being hungover or drunk all the time. I never drank in the morning or at work but I started at 5 pm and didn't stop til I was passed out every night.
Please know it's possible to stop.
