I've never been on Naltrexone, but I was on Campral. It did nothing for me. I continued to drink the whole time I was on it, so I guess there was really no reason to even keep taking it (it's expensive!) I was truly hopeless at that time in my life. What did end up working for me was 100 mg a day of Librium (to detox) and finally getting serious about getting sober. Good luck to you
