@Journeytoletgo i hate to be this blunt, but just stop drinking then. I had a great example of why not to drink in my mom. Never drank more than a sip. But even if you're going to get the shakes if you don't drink, just going to have to deal with the dt's until it's out of your system.
Alcohol is something you have to actively seek out/purchase. It's like the person trying to lose weight who stops at McDonald's on the way home. They went there - no one forced them.
As far as waiting for marriage - idk what to tell you. Some people never get married, some people enjoy the intimacy of sex. Again, at least going forward, you can make the choices that will work the best for you.
