I might have to pass on cardio today unfortunately. I havent been able to take multivitamin for a while now because everytime i do i get VERY sick. I get nauseous, dizzy, cant walk right, and very hot then I throw up. I also had the same reaction to vitamin c tabs. Well i went vitamin shopping yesterday and I picked up some multivitamin for women and I took one this morning and about 20min later I am sick. The only multivitamin I have taken that I seemed to react well with are the children gummy bear multivitamin but that was a while ago. Honestly I am scared shitless to try anymore. Anyone else have this issue?
