If you're not someone who v's easily or often, then I highly doubt it. Not eating can cause you to feel n, so if you're sensitive to that, then yes, you could in turn v. But for me I've had horrible hunger N and although I've felt terrible, it's never made me sick. Just try and sip on some fluids, to at least give you some sort of fullness. If it's possible, try nibbling on some crackers depending on how that feels for you. Best wishes!
