I'm confused about something. I started vaping two days ago. I use to smoke a pack or more a day of Virginia Slims Super Slims (.5 nic). All the juice I have used so far is a 6 (a little), 12 (this is what I've used the most) or 18 (not very often) and I'm not vaping more often than I would have smoked, yet I keep getting headaches. How do I know if my headache is from too much nic or withdrawal because I'm getting too little? Headache is listed as a symptom of both too much nicotine and withdrawal. I'm not dizzy and I'm not getting the buzz I used to when I smoked after not having one for a long time. I don't think I'm way off on my nic because I've only smoked five or six analogs since I started vaping and I'm not craving more. I'm drinking plenty of water and don't show any signs of being dehydrated, so I don't think it's that. I also don't think it's the PG or VG because it only happens sometimes, not every time I vape.
Do I cut back and see if the headaches lessen? Did anyone else struggle with this when they were first trying to find the right juice and levels?
