I finished the course about 10days ago, for me nothing happened aat all until the last week where I found that if I took the humaworm 1hr before eating rather than the 30mins as recommended, I would feel rather odd, but nothing like what you are experiencing. I put it down to the fact it was probably working better. In any case, I never saw anything in the loo that looked remotely parasitical during the whole course, so maybe I do not have a parasite problem. It was just one avenue I wanted to eliminate.....so to speak.
I have read on some forums of people who have had a reaction to it. Its rare, but does happen. However I cannot remember what ingredient it was that was the cause. If I were you, I stop taking them, get your finals done and them re-commence when you have less on your brain. If you think you have had parasites for a while, then a few more weeks wont make that much difference. Thats only my opinion/what I'd do in your shoes.
