eGo Twists vs. mods vs. nicotine withdrawals?

[unable to retrieve full-text content]

ok so after about 4 years of using only eGo twists I finally decided to graduate to reg mods. this weekend was my first using just my mods; an Aspire Zelos and a Tesla Nano Steampunk. but since i vape at work (shhh. nobody knows) i figured it'd be best to just keep taking my eGo to work with me so's i can continue vaping stealthily in my office without having to worry about people noticing big plumes of vape dancing around my head; or the noise, mods are kinda loud by comparison.

anyway...
