I had dizzy spells too Cristina, however, I had been on the 21mg patch for a while longer than you have. I started to become quite ill, very dizzy, very nauseous and I was told by my Health Professional at my doctors that I was actually having too much nicotine delivered by the patch. They suggested I tried the lower dose patch (14mg) and the dizzyness stopped straight away- so it sounds very similar to me Cristina, and perhaps you should try the lower dose. I know that you are probably afraid that your cravings may increase ( I know I was afraid of that), and I guess like Samantha says below you should perhaps seek professional help with that one as I would hate you to jeapordise your quit as it is going so great, my cravings didn't increase or come back thank goodness and I hope yours dont too- please let me know how it goes.
