The fenbendazole is killing the larvae stages that are climbing up your throat to be swallowed to reach adulthood . When I first started treatment with fenbendazole it felt like I had boils or pimples in my throat which eventually went away. New ones will replace the old ones as they continue thru their cycles. I believe the parasites can sense our blood Sugar levels , as we eat , our blood Sugar rapidly rises ringing the dinner bell which is why they get very active when we eat. It also ensures them to be swallowed as we are using our throat muscles to process food and this is probably another trigger for them.
