i can tell you what works for me. on my 30 day fast i used smooth move tea and cascada segrada capsules. also used physillium husks but have heard this is not a good idea because of fiber. now i use Oxypowder and by far it is the best. i have done many 3 ,4 & 5 day fasts since my 30 dayer. and oxy is the only thing i would ever use again. i have no affiliation with this company. im jsut sharing my personal experience.
