i wouldn't start threelac until you've totally finished your parasite and colon cleanse.....these agents can kill the good bacteria that threelac introduces. do one thing at a time. it helps with die off tolerance, too. then after threelac, do some Liver Flushes while taking lots of good probiotics (flora balance, jarro-dophilus, natren, etc.). i've been on threelac for months with incredible results. i am also doing the "body ecology diet" and home enemas and colonics. i am getting well. i hope the same for you.
