Hi Vinny
I won't sugar coat this.
It may get better the longer you stay sober and it might not too.
Im not just talking about the sleep either, talking about the way you react to sobriety.
Look around the forum and you can see in my estimations about a 50/50 split.
For every drinker that kicks on after a few months, there is another who comes unstuck.
Monitor it closely, be prepared to take further action if it doesn't improve.
Sometimes quitting alcohol is all it takes, sometimes it can take a lot more work than just quitting.
Don't underestimate this thing.
