It's sorta itchy, so could it was an infection. I forgot to mention that I've been kinda coughing up some ickiness because of the stupid analogs. It's weird because it goes away after a second or two. It's probably just the e-cig, but I like to make sure just in case lol. Water is definitely awesome, and I drink more of it because of my e-cigarette. So many positive factors with vaping, I'll never go back to analogs.
