There's a lot of people on this website who have completed parasite cleanses.
The best thing for you to do (if you have time) is to read all the results on the parasite forum.
You will be amazed. It's is probably the easiest of all the cleanses and you won't even know you have taken anything.
Usually, the parasite eggs die first and leave your body. They are rice shaped and white. Check out the images section on this website to compare what you pass with the pictures.
The bigger parasites usually don't die off immediately. You may (or may not) experience cramping as they die off and leave your body.
The important thing is not to question side effects. The important thing is to get the free-loading critters out of your body! Ha
