Did you previously smoke? If not, then I'd consider you a "recreational" vaper. You probably should vape 0mg nic
e-liquid.
If you did smoke, maybe you should have started with a lower nic concentration e-liquid.
For e-liquid, the typical nicotine recommendations are generally determined by how much you smoked, and are as follows:
1/2 pack per day or less = 6 mg nicotine
1 ppd = 12 mg
1 1/2 ppd = 18 mg
2 ppd = 24 mg
Should you choose to use a sub-ohm juice attachment (coil less than 1.0 ohm); drop the above recommendations by half.
What type of vape setup are you using?
Symptoms of dizziness, lightheadedness, headache, upset stomach, or jitteriness (is that even a word?) usually means you are using too much nicotine.
