Wow. I didn't even know there was an implant! Of course, that takes the option completely away. I used to play games with Antabuse, moderate with it (holy hell don't recommend that to anyone) and count days until I could drink again...I wonder if the implant is available in the U.S.? I'm over 3 weeks sober now but that sounds like something to consider should there (God forbid) be a relapse.
