Hi Finmywayback,
I commend you your two weeks sobriety and wanting to help your brother.
I agree with other members that you need to set boundaries, definitely no alcohol in the house.
This is your recovery.
It is still a mystery why some of us "get it" and are ready to get sober and others who are suffering so badly don't.
Be an example, be supportive but your sobriety is the most important if you want to help your brother.
I wish you all the best.
