It's not an allergy - an allergic reaction would have presented itself within 10 minute of taking the first dose. It is extreme die-off due to toxins.
There is a couple of ways to tackle this:
1. Back the HUMAWORM dose way down - take 1 cap in the morning and 1 at night. See how this works - it might help to still kill and remove toxins - just not so much at one time. If this seems to work - stay with it for a week or so - then increase the dose to 1 in the morning and 2 at night. If you tolerate this well for another week - then you can increase it back to the full dose.
2. Take Hu-Mana-Tea along with the full dose of HUMAWORM. The tea will help bind to and remove the toxins fater so they won't have the chance to cause so much die-off.
From your description of your experiences with your other cleansings through the years - I have a strong feeling that you are extremely toxic. The tea would really help you with or without the HUMAWORM right now.
