i had the exact same reactions last few times I smoke pot. On positive note, I think it has helped me become more aware of the behaviour of those worms inside my digestive tract and my body. As I believe I have been infected since I was little, maybe even before birth, I used to attribute many internal movements or sounds that happen in my body to being normal. It might take a life time to realize that certain burps are not due to simply trapped gas in the stomach/esophagus but due to an actual big worm partying up and down. Sad to waste a life time to realize those things about ourselves but I am sure I am not the only one as public health education does not really teach us to listen to our bodies or scrutinize what is normal and what is not. Not even so called doctors are trained to recognize those as symptomatology of worm infection
