Bhudson, welcome, good to have you here.
Dump the rum (and all alcohol). It's not fooling anybody. I'd bet even your neighbours could smell it on you from their living room?
.
As a lot of people here have said, you need to want to stop drinking more than anything else. It sound like a throw-away statement at first, but it's similar to deciding to get married, deciding to have kids, etc, it's that fundamental to your life and will change everything.
Briefly, first step would be to consult a Dr, and confide in your husband
Second step. Dump the booze. All of it.
Third step. Work through the withdrawals (whichever method you want to use / been advised to use)
Fourth Develop and refine your plan.
Simultaneously to all of this, stick close to SR. This is where the specialists in alcoholism and recovery hang out. And I learn from them every day.
All the best,
Bruce.
