This type thread always calls for my patented reply.
Your friend will not take you to work or pay your SR-22 insurance when you get a DUI.
Your friend will not throw up blood for you when your body finally has had enough.
She will not pay your bills when you get fired.
She has her own hangovers to deal with so she will not take on yours.
Let her know how you feel and if she can't handle it then end the friendship.
