Well I finally got my first vaping experience with my 510! Sorry for the long post in advance, I wanted to share my experience and have some questions as well. First of all, I should have listened to you guys and got both of my batteries in manual. Do you know what's more annoying than pushing a button to vape? Having to take 3 or 4 fake puffs just to get anything. That and the fact that at first I was like, where's the vape, I'm not getting anything, with my automatic battery until I figured it out. Other than that though the manual and auto seem pretty similar. I'm really liking it so far, and have only had one analog since last night when I started. I made the mistake of ordering 3 bottles of 24 mg thinking I'm a pack a day marlboro reds smoker, I must need the strong stuff. Now vaping on the 16 mg that came with my kit I'm getting a good nicotine buzz so I think 24 will be too strong. That's my first question, am I supposed to be feeling a good nicotine buz with the right mg's? Don't get me wrong I'm loving the nicotine buzz and it's really helping with the craving for smokes, I just don't want to get even more addicted then I already am to nicotine and am wondering if the 16 mg is too much. Also how hard is it to cut your e-liquid down? I'm a little nervous to try mixing, but now I have 3 bottles of 24mg that will be too strong. Thanks so much for taking the time to read this.
