Ok so I just started on rda. I have been vaping on Ego w/ Dual coil cart w/ 24mg nic. It was making me dizzy in rda. So, I pulled out some samples from MT. Baker and using them in RDA. Stopped by B&M today and he said I need to estimate whatever nic level I'm using in RDA and double it, is this true?? So in reality my 12 mg labeled is actually 24 mg when using RDA? He also said the 12 mg is really high w/ RDA. He said most people using RDA go no higher than 6 mg? Any help would be appreciated!
