I've started cutting my nic level from 12 to 6 recently. I am still vaping 12 of GCD every day in my nautilus but 6 of Virus in the Reo. I was in the mood for some refresh so I loaded it up in a Kanger Aerotank. First hit I got dizzy. This has never happened before! I waited a few minutes for the feeling to pass and tried again. Same dizzy feeling. I emptied the tank and cut it with NZ and it's much better. What the heck?? Why is GCD fine and Refresh isn't? It makes me sad as I have a lot of 12 mg juice. Looks like I need to trade or order more NZ.
