Comes from your stomach
Your stomach is on slow motion
The shot slows how fast food leaves your stomach. That's how it keeps you full. But food that sits that long starts to ferment. Gas and acid push back up, which is why so many women on the shot get sulfur burps, reflux, and a sour taste rising in the back of the throat. That smell is coming up from below. A toothbrush can't reach it.
