Am on day 5 of champix and just gone to two pills a day - smoking a bit less but feeling very weird and quite light headed. Also am majorly freaked out as just come back from a trip to the docs where they took my blood pressure which was very VERY high. In the past it has been slightly on the high side but not in the 'concern' area. Is this related to champix or do a I seriously need to change everything else in my life as well as smoking??? Why is is that most of the pleasures in life are bad for you......? Anyway, the serious question is, has champix affected your blood pressure at all?
