Hello Larry. Thanks for the information about the difference. I kinda figures the shot would be condusive for TSM but I wasn't completely sure. I do live in the states so I'm going to make an appointment with my Dr. and see if she will prescribe me Naltrexone. the places that I found online that specialized in Vivitrol don't mention Naltrexone (pill form) so I don't know if they prescribe it. I know that it will be lot cheaper to do it that way than to get it from overseas. Thanks again for responding
