Due to stress and personal problems I started smoking again. First it was just a couple cigarettes a day mixed with vaping. I slowly started to smoke more and vape less. Now I just smoke and when I try to vape I either find it unsatisfying (pre-built coils) or stop becausing of coughing and throat irritation (rebuildables). I would like to get back to strictly vaping since I've been less stressed but haven't been successful because of the previously stated problems. Is there anything I could try to lessen the irritation and coughing (sometimes coughing up phlegm) I get when using my rebuildables?
