Caszee I'm very sorry about your youngest child, that must be so hard.
My drinking story was similar to yours -- a bottle of wine, then a bottle and a glass, then a bottle and a half and so on. I had that weeny bit of control too where I'd stop (most times) so I could "function" the next day but could kill for an afternoon nap which I very rarely could have.
It all stopped 51 days ago, just over seven weeks. My health has completed turned around, I'm far more energetic and I sleep well at night. I get so much done each day I stun myself.
For me the big thing was not to just take away the wine but replace it with non-alcoholic options and different things to do. You can do it.
