Hi asia - good to hear the Paragone is working for ya! The red things are probably liver flukes if they aren't remnants of food - check out some of the pictures, or google/hunt the web using key words of flukes, parasites, pictures, etc.
The herbs are formulated to help not only kill, but help the kidneys eliminate the dead parasitic waste. Thus, the newfound ease in urination. (Same with bowels.) Lots of great herbal remedies for trouble in urination - worth checking out. Our homeopath doctor has even helped my mom, who has nerve damage that inhibits her bladder and kidney function, with his herbal brews.
Tiredness is also a side effect, usually more so at the beginning when parasite
die-off is occurring. You may also feel like you're "coming down with something" - don't worry, the fatigue and icky feelings will pass, and so will many of your parasites!
