depression
"After the first week I felt more cheerful and energetic.  After one month I completely lost my craving for cigarettes. (I was a social smoker, maybe would have five a week.  But when I wanted one the cravings were intense).    However my blood pressure was elevated  157/110. (I am on lisinopril-HCTZ for that). My sister was sure the bupropion was causing my high blood pressure. After a couple of weeks my smoking cravings came back and my blood pressure was still elevated so I went back on bupropion.  Second time around I am super cranky and have a heightened sense of smell, but still crave cigarettes."
