IN order to "end up " worse, you would have to define end up.
Does that mean someone feels a bit yukky right after finishing a round? could. Humaworm gets rid of parasites but there is further work to be done , to restore health, for many... such as regenerating weak tissues , cleansing out toxins, establishing microbial balance... Also, the very process of doing something of this nature raises awareness, and could bring people out of the haze they were in prior, so that they are now aware of the actual state of their health. I think for many, a parasite infestation is the wake up sign that drives them to do a cleanse, whereas they have been sub-par for many years (fat, tired, bloated, weak, in pain)... once the parasites are gone, there is more health restoration to do.
