Yes, it "is" tough to get through this challenge and you are right, it is very lonely. That is why I am glad you found PC, and I suggested also finding some alanon meetings too.

You mentioned that your husband is going to try going 90 days without? Well, if he has been drinking every day be careful, he could experience some bad withdrawls.

It would be better for him to go to AA meetings, he really needs to know he not only has a problem, but he can get a lot of support to learn how to live his life without the alcohol and become much happier as a person. His disease is a lonely one too.
