Welcome to TheSinclairMethod and congratulations on getting started with TSM, Kinsugigirl!
Just as a heads up, the board had grown pretty quiet these days and you might want to check out

I don't know how much info you've read on this, but the best way to get going is to wait till you have the next day off, in case the side effects are inconvenient. Start with 25mg on top of at least a small meal for a few days , then if the side effects are tolerable, move up to 50mg. No matter the dose, wait an hour after you take the pill to begin drinking. Follow up the dose with plenty of water throughout the evening to minimize the side effects. Once you get past the side effects, you can take the dose on an empty stomach.
You may get the feeling at some point in the evening that you are on the fence about having another drink. That's your brain telling you that it's probably had enough alcohol for the night. Seize that opportunity and switch to a NA drink for the rest of the evening.
Work on stretching out your drinks, even to the point of leaving them out of reach while you keep a NA drink close by your side. It helps to work on teasing out the difference in how you feel when you actually crave another drink as opposed to simply wanting one. If your brain simply won't leave you alone till you give it another drink, that's craving.
Another important point is to wait to take the Naltrexone till you actually crave a drink. This will set the brain up to really anticipate the blast of endorphins and it will get the maximal disappointment when you keep the craving, the dose of Nal and, after waiting the hour, the first drink as close together as possible.
Oral Naltrexone is available in South Africa, but you may have to do some asking around. Hopefully it will be less expensive than the overseas pharmacy.
