Ok, I'm new to vaping. I smoke a pack to a pack and a half of Marlboro Lights a day. My goal was to quick cigarettes all together and just vape. I have started with the blu to keep the testing cost down. Here is my problem. After about a day on the blu medium carts, I started getting headaches and my neck began to ache like crazy. At first I thought it may be too much nicotine and then began to wonder if it was the PG. I don't believe I am over vaping. I am using the blu like a standard cigarette. 10 to 15 drags and I put it down. I have ordered the Johnson Creek low PG smoke juice and I like it. HOWEVER, I am still getting monster headaches. Their sample pack comes in 24 mg of nicotine only. I also cut it in several different methods, but that didn't work. Does anyone have any suggestions or recommendations to help me out.
