I have the KR808D-1 and have several e juices from freedom smoke, wyatt earp, purecig max boro, ect but last week I noticed that they seem to have gotten harsh on my thoat and then I started to get a sore thoat and now a cough and can not smoke them because it hurts. I can smoke the real cigerettes though (I have to because I can't smoke the e cig) Is it the ejuice? I have both 24 and 30 mg nicotine and I also tried using the 16mg that came with the ecig and they are just as bad. Also - I can not smoke the sweet flavors because I don't like how they taste. Do I need to give up my e cig or am I doing something wrong. Please help as I really don't want to smoke the analogs!!!!
