I just wanted to ad that MANY of the parasites we are chasing,...look like small seeds! (Sorry to burst your bubble).
Tapeworm segments come to mind,...they look like sesame seeds, or as large as almost slices. Then,....the eggs also look like seeds sometimes. If the answer to the last posters questions are that you feel awful,.....those are parasites you are already passing. So, you're well on your way and your program is at least working. If I'm right!
