I first tried vaping 3 weeks ago, KGO starter kit, and it went well, however I was just recovering from abdominal surgery, and it was not the best time to start, so I was vaping and smoking. Now that I am pretty well recovered, I find that the throat hit is just too much to take no matter what flavors I try. I cough every time, and that is not so good after my surgery. So far all my juices are from one source, no breakdown of VG/PG is given. I am 77, and have been smoking since I was 13, and would really like to get off the smokes, but if I can't vape without the congestion and coughing I don't think this is going to work. I have looked in at Backwoods brew, and Copper Creek and I can pick my own VG/PG ratio, but I don't have a clue as to what ratio might help. I now have a Provari and have tried lowering the voltage a bit, and am using both single and dual tanks, but so far it hasn't helped. any ideas about decreasing the throat hit (actually more like lung hit to me) would be appreciated.
