I'm not sure if it'sor Smolder I'm getting this effect from, as I'm stacking them, but I've noticed upon application, I get a warming sensation, then it goes away. However, when I eat something later, the warming sensation comes back. Not unpleasant, just very noticeable, having totally subsided before. This happens whenever I eat during the day, even many hours later. Is that normal? Why does it happen I wonder?
