Hi all. Finally got my mom to try out ecigs. She's been a smoker (2 1/2 packs a day of any cheap ultra light 100's) for 50 years, so we thought the higher nicotine level would be needed...I'm fairly new to ecigs as well. Well, she got her Vapor King in yesterday and a bunch of 36mg Cowboy cartomizers and she says she has had a huge headache ever since her first puff. I guess we may have gone a bit high on the nicotine level. I'm afraid of going too low because I know she'll just go back to analogs if she isn't getting her nicotine. Based on her analog intake, any suggestions on that sweet spot as far as nicotine strength is concerned? Thanks in advance.
