I had an Naltrexone implant 3 weeks ago! From drinking whisky @ 5:30 in the morning slugging slips and finishing a bottle a day, the first 2 weeks after the implant I stopped drinking but the last week I have been having 2 double whiskys at night. Very scared about that, the implant has made me drink less,,, I want to know if I have to take implant continuosly if I carry on having 2 drinks @ night.
