alcohol dependence
"I spent 2 years in and out of AA.  It was miserable.  I was not an "AA person" at all. In fact, AA meetings made me want to drink.  My doctor put my on Naltrexone.  It worked immediately.  It actually worked too well.  I no longer craved or thought about alcohol but I also didn't like the taste of food. I lost interest in sex. I lost interest in being physically active.  I was spaced out constantly.  It was not living at all.  So I went off of Naltrexone and resumed drinking.  
When I was ready to try giving up alcohol again, I went back to Naltrexone BUT only took HALF a pill a day.  This made a huge difference.  I still feel as though I don't enjoy many things like before.  But I don't have the option to drown myself in booze."
