Hi SmilinMike congrats on your move to give up the ciggs. Today is my 7th day of vaping. I was having a lot of coughing going on and it burnt my throat every time I vaped. I started out with 24mg of nicotine. Yesterday I bought some new juices with lower nicotine and no coughing or sore throat. These threads have been so helpful to me and everyone here is so nice to answer our questions as newbies. I think like so many say here it's trial and error and takes a little time finding the perfect blend of nicotine, vg/pg, E-Cigg, and E-juice. Good luck.
