I have recently quit cigarettes cold turkey because I got a halo triton and I love it. It has been about 2 weeks and my throat is soar and I can't sleep because of so much coughing and brownish phlegm that I spit up. I am sure it's just my lungs clearing the selfs out but what I have noticed, is if I vape for 10-15 minutes on my smoke breaks at work at the end if I take a deep breath I almost gag. Does any one els have this problem? I never throw up or anything but it's weird because it normally only happens once .
