I'm really really enjoying my 2 piece e-cig. I only have one problem, I vap so much that i need to get zero nicotine cartomizers. vaping with nicotine cartomizers give me a headache and make me a little nauseous sometimes. I'm using 16mg to 11mg of nicotine. I have a few zero nic carts, but finding any zero flavored cartomizers has been almost impossible. I'm hoping someone can give me the heads up on suppliers who carry these. My e-cig is a KR808D-1. I am interested in 0 ,2,4 nicotine cartomizers inflavors. Any help would be most appreciated
