Thanks LFC
Sadly sounds like your friend is on the way back to moderation.... With all the attendant hazards for people like us.
If it were my friend I might feel empowered to find a way to mention the warning signs. In doing so I would be mindful of 2 things.
That our friendship might 'cool' irrevocably as a result.
And to keep my expectations real. We all know how powerful the self delusion and denial can be.
Above all, if I felt that my sober safety was endangered in any way, it would have to be the end of this.
These situations arise in sobriety and hope that you find a way of dealing that sits comfortably with you.
