I physically feel like I haven't had a cig all day. That tingly lung-y, "Man I need a cig " feeling. Cravings real bad, but if I start to smoke one, I feel like I am getting too much nicotien.
I think the majority of what you're experiencing is the process of psychologically breaking the habit.
Your brain is telling you that you're supposed to be smoking, regardless of how much nicotine you've had. It will go away with time.
If you were saying that you were not sleeping well, were having sweats, cramps, etc. Then I'd say you were having withdrawal symptoms of the physical nature.
All of that will pass, though. You've just got to soldier through.
Not everyone goes through what you're going through.
To be honest, when you really REALLY want a cigarette, smoke one. Sometimes, that's what makes people realize they don't want to burn analogs anymore. They start to taste awful over time, and you begin to wonder why you liked them in the first place.
Just don't buy any more packs. Continue to smoke the ones you have on those occasions where you really can't stand it. When those run out, you'll probably already be in a position to make the full-on switch to e-cigs.
