First of all I wanted to say hello to everyone. I am really grateful that this forum is here! I used to pass by the ecig kiosk in the mall and think it was a scam, then my friend told me about it. Of course my research led me here and you guys convinced me to try it. I bought my first ecig on Sat and I have been using it since, although I have been smoking like 2-4 analogs still a day. I am getting some headaches. I thought maybe it could be the other chemicals in the analogs, or maybe I am getting too much nicotine, although I am using a 2 piece ecig with 6mg cartridges..Has anyone else gotten headaches when they first started? Just curious. Thanks so much!
