Thanks for all the quick responses. After reading, I have determined that its because my frequent hits coupled with my constant smoking of analogs that is causing my migraines. Once I slowed down on hits and stopped smoking analogs, things got a little better. I have headaches that are less severe. Im thinking the guy at the shop might have mixed it with a high mg level of nicotine then he or i intended. Therefor giving me a "overdose" of Nicotine. With that and the frequent hits caused this whole issue. Im going to buy more with the lower level and see if anything gets better.
BTW: No.27 is like a medium strength cigarette, most comparable to a Camel red then a Marlboro red
