well, As my feeling great overall is I mean I can tell its working. I get muscle twitches in my legs and my nose.. I am feeling soooo relaxed a few hours after taking... I sleep better.. I just know that the head isnt dead yet because my vision will clear up when it dies.. The reason i know this is because i killed one using CoQ10 and all of my symptoms went away as soon as it died.. Not sure if I was reinfected from the eggs in my intestines or what, but now I know there is another one there. I just ordered another bottle to have after this round is up. I will use this whole bottle (150) which should last me another 4 rounds. even if I kill this thing im going to finish all of it just in case another tries to reinfect me.
