It seems like the same story different day, chef.
Same thread (or same theme) from years ago.
Is there some reason why you can't take (say) six months away from the job to get yourself straightened out? I believe you can live the life you're living without drinking, I did something similar for years and it is a dream job for a chef so I can see not wanting to let it go. There are also lots of land-based jobs in tropical paradise.
You can go back to it and stay sober, but I feel like you may need to sort out the drinking part without being in the job. After a few months sober, all of this will make a lot more sense. I hope you do something this time.
If your current employer has all this money would he/she be willing to help you sober up by sponsoring you into a rehab and then giving you your job back?
