My Experience with Digestive Enzymes

So I read on this site that you could take bromelain or just eat pineapple on an empty stomach to kill parasites. Not sure why I decided to experiment with it today. I ordered some Digestive Enzyme capsules made by Source Naturals over a month ago..and have to yet to try them out until today. I initially ordered them because sometimes I have trouble digestng my food. Anyway, this capsule has bromelain along with other enzymes and even ginger root, peppermint and black pepper. I didn't take it on a fully empty stomach because I had eaten a biscuit at least 2-3 hours before. BUT I did take it at least 2-2.5 hours before lunch. Thirty minutes later...um stomach just felt weird...I felt something moving(worm?). Then I felt drowsy. I was contemplating leaving...because I got weird feelings from my stomach to my thighs and a little acid reflux. I decided to take my one hour lunch and went ahead and ate my sandwich, cheese crackers, and drunk my coke. I decided to not to go home...because I felt better. Then fast forward an hour to hour and a half and I'm sort of nauseaous and sleepy again. I decided to leave opting to go to the pharmacy to pick up my last prescription of promethizine (because I DO NOT want to upchuck a half digested worm if that's what it is.)...Um...I'm still feeling a little queezy in the tummy...and had a small bout with hiccups. UM If THIS LITTLE DIGESTIVE PILL IS GOING TO DO ALL OF THIS AND MAKE mE FEEL THIS WAY...THEN I CAN ONLY IMAGINE WHAT THE parasite KILLING HERBS WILL DO AND MAKE ME FEEL. This is NOT the business. This little experiment lets me know that I need to take off work for full month if I'm going to do this with herbs...because um I can't take it...and unfortunately I can't take off unless I have a doctor's written orders. Guess parasite killing is not going to happen anytime soon.
