Does this make sense? Die-off?

Hi, I am 3 weeks into the candida cleanse and I'm getting bad fatigue throughout the day, which seems worse after meals. I'm getting body aches, too, but the fatigue is worse. I'm not sleepy with the fatigue, it's more like I feel it deep in my bones. It comes with a little nausea, too. Why/how would eating affect die-off? Is it my liver that's being stressed?

Also, I can't afford to buy the Humana tea right now. Would any detox tea from the health food store be okay? Is there a specific ingredient that's most important to help bind toxins?

Thank you.
