I have read various negative things about using 36mg or 48mg liquids. Using the Totally Wicked Titan Tornado mega-battery along with a LR atomizer, I have been using 16mg, 24mg, and 36 mg, Dekang liquid (Camel and Marlboro VG). I found a supplier in China with great prices, even with the higher shipping charges. I decided to try 48mg, also Camel and Marlboro VG, sold by My Freedom Smokes. I find that, with no negative effects whatsoever, it really satisfies me. I alternate back and forth with the different strengths and even mix the two flavors together. I never feel dizzy, and my BP and HR, checked with a cuff meter, stay pretty steady. To avoid the 'cotton mouth' feel, I generally use Walmart spearmint lozenges as I vape. Dry mouth and throat do not seem to be a problem. Oddly enough, I hadn't smoked in over 15 years and always missed it. vaping seems to be the ideal solution. No smell, no headachy feeling caused by smoke, and a total nicotine satisfaction. Maybe I have a high tolerance level but, for me, the higher strengths really do the trick. I only vape at home, relaxing in front of the TV. I feel no need to do it when I am out and about. Has anyone else out there tried the higher strengths and feel the same way?
