Keep your head up Sweetie...most first timers don't make it to the fifth day! Give it time...trust there are some major changes undergoing in that machine of your's...keep in mind your life's habits may be different than the other people doing the cleanse, so you can't expect the same experience...
I myself don't have bowel-movements throught the day as well after the SWF...before going to bed, I'll get a nice lil' elimination. Mostly mucous, caniene pepper and lemon pulp...
Sounds to me that you take pretty good care of your body, so don't worry if you don't see any parasites!
