Welcome to TheSinclairMethod Spirit and congratulations on launching your TSM journey!
The side effects you mention aren't unusual. I can't recall exactly, it might have been a week till this faded but I think it was only a few days: When I took Naltrexone, I got cranky right away. Felt like kicking the dog, but fortunately I don't have one. But yeah. Pissy mood for sure. Best way to work past it is to take the pill on top of at least a small meal, then follow up with lots of water throughout the evening. The side effects generally pass in 3-14 days. Some of it could be from a sudden decrease in drinking (I don't know how much your were drinking pre-TSM), but I felt cranky even before my first drink on Naltrexone.
There's a whole range of side effects from starting Naltrexone, some get cranky, some sleepy, some foggy, some anxious and some relaxed. Some get no side effects at all.
Sounds like you're seeing a quick drop in your drinking, just be aware that there is a "Honeymoon" phase and you will likely see a rebound after that. Drinking levels rise and fall throughout TSM, but it seems most pronounced at the beginning. Just keep taking the pill an hour before your first drink and it will settle back down. The upswings are generally due to the addicted part of the brain reaching out harder for it's "old buddy".
Tracking your drinks is a really good idea with TSM, here's a spreadsheet/graph combo you can use:
