So how do you use Nicocure patches? To get started, you simply need to put one of the patches on your body. Preferably on a mostly hair free area. The patch is worn for 24 hours. After the 24 hours, just replace it with a new one. After no more than 10 days, you should find your cravings are just about gone. The company recommends to keep wearing the patches for a full 30 day period to ensure your success.
