creepy sensations & colonix

I've been on colonix program (paranil, fiber & tea) for about 1 1/2 months. It has been working well enough for me in terms of bowel cleansing. However, throughout this cleanse, nearly every night around 1-1:30 am, I wake up with the creepiest sensations...a sort of annoying strong tingling sensation that (is difficult to decribe)... centered throughout my abdominal area, sometimes radiating through to my legs. It does subside after about a half hour, but it is very disturbing and difficult to shake! I did take a break from the paranil & tea after the first month of cleanse (as suggested by Natura). During that week "off" -- no "night sensations". From what I understand , TCM designates 1-2am "liver time" . Any ideas as to what is going on ?
Thanks in advance. Tweet
