So its about day 10 since I've had an "analog" cigarette but I've been steadily vaping at 12mg nic level since. I've been a little nauseous some days and overall fatigued but what I have noticed the most is my inability to sleep past 4-5 hours a night! I haven't really found this to be a symptom of cigarette withdrawal online. Did anyone else experience this when they quit? I have no problems falling asleep, but I'm used to sleeping between 6.5-8 hours a night. It seems that since I've switched to vaping I wake up every morning now around the same time after 4-5 hours of sleep tired as hell and unable to fall back asleep.
