Hi Plenny,
Wanted to lend my support to you in this sad situation. Be prepared for your friend to treat you as the enemy when you set these limits. Anything that comes between an alcoholic and their drink can be seen this way. Try not to take it personally, hard though that is. You should not feel guilty for taking care of yourself, ever.
And I second (or third) the Alanon recommendation - be it meetings, or reading the literature - I found it very helpful in learning to detach from my loved one's downward spiral.
Good luck,
SQ
