Help needed for 1st time cleanse, & magnesium carbonate

Hi, I just got this product off Ebay:

http://cgi.ebay.com/Parasite-Worm-Fungus-Cleanse-NIB-FREE-SH-Powerful_W0QQite...

Can anyone give me some pointers as to how to make the cleasing process smooth as I'm a first-time cleanser.

At the moment I'm taking in the morning, with empty stomach, magnesium carbonate(MgCO3). It's a refined white powder that looks like very refined white flour. My menthor who passed away last year had recommended it to me as a general cleanser. Does anyone know the medical effects of this powder because I couldn't find anything on the internet. All I can say about this powder is that it has a laxative effect and makes me go to bathroom 1 or twice a day, sometimes 3 or 4 times a day. It also liquifies the stool.

My question is, should I take the parasite cleanser alone or take it with magnesium carbonate?

Thanks
