One of my reactions recently was to a fiber supplement, psysillim husk in wAter and immediately upon taking that supplement, my blood pressure dropped, pulse raised, i had to go to sleep and it actually caused muscle fasiculations. I had another reaction like that recently to Cortef as well. I have had this reaction so many times since 2007 all of them were to ingested medications or chemicals except for I had the same reaction to CT dye that obviously was not ingested. I had this reaction in 2007 to a store bought cupcake with tons of food dye and preservatives hives, I got dizzy, high pulse raced, too many symptoms to list. Hmmmmmmm
