Hi every one i am new to vaping just wondering does any one had a slight headache when you all vape? i keep having this slight headache after i vaped and i think its weird. Its like i having too much nicotine(and i taking only 2-3 puff per time). Currently i am using only 14mg level of e-juice and later i change to 11Mg of e-juice and yet i still have this problem. 
Do you all have it when you start vaping?Is it normal? pls help and thanks!
