imfedup,
I understand where you are, I really do. I was married to an alcoholic who couldn't stay sober unless he took Anabuse. Now that we understand each other...let me say this.
Please don't take it upon yourself to force feed him that stuff. It's really dangerous and it's not going to help him.
If he takes the Anabuse, in the hopes of staying sober...that's all well and good. But you can't manage his sobriety. That's his job.
Slipping Anabuse into his food when you know he's drinking is just going to make him sicker than he already is. And that is not a solution to the problem.
You can only work on how this is affecting you.
Check out the Alanon and Naranon forums here. There are a lot of people who can offer you encouragement and support.
