I found green smoke to be kind of nasty after a few days, and a complete waste of money. My suggestion would be to go to domesticvapor.com (they are the only vendor I found who had the kit with the mega battery.) and get an eGo kit. Then go to cignot and get some juice. As far as a dry cough, well different people have different reactions. Green smoke kind of irritated my throat, and I find mostly PG ratios are kind of harsh for my taste. I have no doubt if you find the right juice you will be very happy. I can highly recommend backwoods brew as well. search around and contact him on this forum. I'm sure he can make a juice to fit your needs. May take some trial and error, but so worth it. Feel free to contact me if you have any questions.
