Well, perhaps, step back a minute and consider what this med does... It blocks those receptors that are looking for alcohol... this is biochemical, you know... The receptors do have to change once we aren't feeding them alcohol... and they change back... on a biochemical level...
Cravings are, as I understand them, physical, biochemical... all that. That is where naltrexone may help you...
That other stuff... loneliness, anxiety, frustration, heartache, all that... IDK how naltrexone is gonna help you, in the long run.
