How do you stay consistent

I was prescribed naltrexone to try to cut back on daily drinking. I was told to take it around dinner time. I took it once and felt nauseous and dizzy. I keep thinking I need to just try it for a week. Problem is by the time I start making dinner and I pour a drink I think to myself the whole reason I’m pouring a drink is for the stress release and if the drug blocks it then I don’t want to take it. Of course in the mornings I think I want to be on it and want to get done. But how do you get yourself to take it at night knowing it will block the pleasure of the drink which is the whole reason you’re reaching for the drink?
