I used telemedicine to get my first prescription. I had a few appointments and probably talked to the total for about 30 minutes in total. The Sinclair Method is pretty straightforward once you understand it and there is only one hard rule (always take Naltrexone at least 1 hour before consuming alcohol). But the doctor will want to do a liver enzyme test and ask some basic questions to make sure that it is safe for you to take Naltrexone. If your liver is damaged, you may have to take Nalmefrene instead. Or if you are using opiates, it can be unsafe to take Naltrexone (not sure of the details here).
At some point I was able to get my PCP to refill my Naltrexone subscription. Naltrexone is pretty widely known for treatment for alcoholism but the prevailing wisdom in the medical community is that it must be taken every day to prevent cravings and alcohol should not be consumed when on Naltrexone. I've heard that this way of using Naltrexone isn't any better than placebo. The TSM book[1] does a good job of explaining why this is the case: the mechanism of action is that the Naltrexone blocks the endorphin rewards from consuming alcohol, so it doesn't work if you don't drink and there is no point in taking Naltrexone without drinking.
tldr: you may be able to find a TSM specific doctor via telemedicine. Additionally, most PCP will probably prescribe Naltrexone, although you need to be mindful that they may recommend to take it every day and this is not TSM
