I have a completely different reaction to the HW I just purchased a couple of weeks ago too. When I did this a few years ago I saw a lot of parasites (and different kinds) and had very few side effects. This time I only see a few of the ones like you described but not much at all. Also I have more side effects. I was wondering if there could have been a slightly different formula made recently or if one of the ingredients was from a new source. Maybe this could just be that the majority of the parasites are gone from the previous rounds causing this effect instead.
