I am officially going to partake in the world of sub-ohm vaping. But first, allow me to introduce myself. I just made an account like a minute ago, after I Google searched nicotine levels for sub-ohm tanks. My name is Andy. I am 18 years old. I started smoking cigarettes at age 15. I'm not a bad kid or anything, but I also haven't smoked in nearly half a year. I need nicotine to inhale, as my Asperger's make me somewhat OCD about my nicotine intake. I started out vaping about eight months ago. I first started out with a tiny Joyetech pen, then two months later my uncle sold me a Joyetech 20W Ecom Mega. That is what I have been using since. Moving back and forth from 18-12mg, I started to develop the aweful vaper's tongue. This took months, of course, as I go through about 5ml a day. Anyway, my friend Ryan was using something about 6 months prior, during the school year, which he referred to as a "sub-ohm vape." I lost touch with him but I think I found the tube mod that he was using. An Ego One XL by Joyetech, which I just ordered 3 days ago and am patiently awaiting the arrival of. I'm stoked, I even bought a 5 pack of 0.5 ohm coils, and (if I'm not mistaken) the brand new box should come with both a 0.5 ohm coil, and a 1.0 ohm coil. I'm always broke where I live and was lucky enough to receive a debit card with $50 on it for Christmas. I paid $29.99 for the Ego and over $12 I think for the pack of coils. If anyone can reflect on their own personal use of this device, please do so. Also reflect on what I am to expect, since I've never owned a sub-ohm vape. In-depth information is very much appreciated. I'm a very friendly person and looking forward to becoming an active member of the vaping underground community.
