I'm quitting. I vaped and smoked cigarettes and cigars. I started using patches 8 days ago. I'm on 14mg. They weren't causing me any problems until the past 2 days. It was fine at the beginning. Is it possible that it is somehow too much nicotine now? I have felt nauseous and had a constant headache when I put them on. What do you think? Do I need to go lower now for some reason ?
