I just started taking it a few days ago. I ordered a 6 month supply(they had a deal) but now think that it's probably not necessary to be on it for so long(I'm planning on doing the master cleanse once I get some time off). The only things I noticed after two days is less gas(still there but not as bad as before) and for me, two extra bowel movements in the morning(mostly diarrhea). I debated between this and colonix.
