I am in a similar situation. I just spent several days talking down a great person from suicide over alcoholism. Got her in a facility - Im also a bad drunk - I have been told I am a functional alcoholic.
I am just slowly dinging from drinking - shakes every day etc. I am ready to stop - I have before it just doesn't stick. Its been a very rough road.
I've always had an interesting relationship with drinking - two speeds are "go" and "faster".
Taking a month or so off is a good way to reset, but that doesn't change things forever.
I'm highly functioning, but that was slipping.
The need to check my call log/messages/sent emails the following morning was a strong sign that it was having more of a negative impact on something I pride myself on.
I've just done Dry July again for the 4th time - usually with another month during the year to "prove that I don't need it".
In truth, taking the month off was nothing more than "holding my breath" for a month. It's easy to do to get short term benefits.
This time around though I had crashed and burned prior with depression caused by the death of my mother and a close friend inside a few months of each other.
My behaviour was poor towards my friends, employees and family - and I had other issues with grief that needed to be addressed.
I started SSRI (antidepressants) for the first time in my life, as lifting, seeing a shrink and being dry weren't going to fix things this time.
It has been a massive help, and currently I don't have the desire to drink like I did.
In summary, asking for professional help is a great way to start the process - even if is just your GP.
This applies regardless of whether you want to 100% stop, or just get things under control again.
