Welcome Thirdwave. Great group with a ton of unconditional support here at SR.
I was able to hide my alcohol consumption from my wife, kids and close family / friends for years; at least the level of my consumption. Spent 20+ years drinking heavily but functioning at the same time. Things progressively got worse until I was drinking in the mornings and at work.
I couldn't do that any more, it was ruining me from the inside out.
Good job on making the decision to quit. Now comes the hard part but the part that will give you your life back... the commitment.
You can do this. Reading as many threads and posts as possible and posting often has helped me stay sober.
Lean on this community as much as you need.
Best wishes.
