I feel nausous and vomit every time I smell popcorn. Not the kind you buy already made but the kind that is freshly made. i.e. theatre popcorn, Reddenbakkers...etc. My work had to transfer me out of one department into another to get me away from the smell. But, now my hours have dropped. I need something that will block the reaction from happening.
Gravol is supposed to quell nausea and vomiting no matter what the cause. I know I have used it a couple of times when I have been ill; and, it has worked quite well. I see no reason it won't work if you take it before you smell the popcorn or very shortly thereafter. The only true test is to try it and see.
