Loose stools after eating... Humaworm or IBS symptoms?

I took Paratrex a couple months ago because I was worried I had a parasite infection. When the symptoms kept coming I decided to take Humaworm, but I have to admit I have not taken it regularly. I began to seriously doubt that I had any problem with parasites so I stopped it for a few days. Then I decided to start it again yesterday. It never seemed to cause problems before, but yesterday and today I have had stomach aches and loose stools (not watery like diarrhea but looser than normal) soon after eating. Yesterday it wasn't until I ate the second time and today it happened after the first time I ate. Also today when I took it I felt burning in my throat.

Are these symptoms normal with Humaworm?
