Amy, been followin' ur delema, went thru the same thing w/the tightness & coughin up some "junk" when I first started a couple months ago, it gets better I promise. It's like ur lungs r n a "healing process" or something. I smoked 1&1/2 pad for 25 yrs & when I picked up my joye 510 it was all over with!! Not looking back now & never will!! My lil' boys ( 23yrs & 7yrs) also r soo glad that I quit analogs! My 7 yr old says that I make the house smell good ,heehee. Joogler juice is where I get my juice from, "Andrew" is the nicest guy w/great customer service!! Fruit Stripe Gum is my choice, he has really fast service too, got my stuff in 2 days! 
Good luck & welcome to the wonderful world of vapor!!
