The original poster had a couple of symptoms, all of which can be explained by a panic attack.
There is no reason I can see to assume there was too much nicotine involved, especially when there was no nausea or headache.
The original poster used to smoke a pack per day of cigarettes, and probably now uses a fairly ineffective cig-a-like.
It would take probably at least 6 cartridges per day of 8mg juice to get the same amount of nicotine her body is already used to getting.
Probably more like 8 to 10 per day depending on the size of the cartridges.
My thinking is that the original poster was WORRIED that she was getting too much nicotine, which caused the panic attack.
In reality, the amount of nicotine probably had nothing to do with the panic attack.
It's more likely to me that, from a review of the evidence, she is not getting enough nicotine and that is why she is still smoking.
And in addition to that, she should stop worry about getting too much nicotine at this point.
I'm putting on my flame suit now.
