hi. i started taking Chantix on Jan 14th. I stopped smoking on Jan 21st(7 days later as recommended) I have not smoked and it is definately working. The only side effect i have is nausea sometimes and EXTREME tiredness, laziness, basically lethargic. this is weird for me because i am usually super high energy. i definately think my tiredness is from the medicine. it is good to know others are feeling the same way, as i can be a hypochomdriac at times. my doctor told me that since i am doing so well with not smoking, he is going to keep the dosage as is. i just wish i had more energy. i just want to be in bed all the time. ahhhhhh!!
please respond back!
