PG will dry you out, VG will moisturize and give you the thick and heavy feeling. Therefore it makes sense to stick around a 50/50 ratio, unless you have a pg allergy.
Being asthmatic, nicotine plays a HUGE role in how your lungs will feel. The higher the nicotine, the more they will get irritated. I know this first hand. When I started vaping 15 months ago, I started at 18mg on a ctwist and a cheap ce4. I am now down to 6mg on drippers and sub ohm. My lungs thanked me. Night and day, nicotine strength affects your lungs.
You need to wisen up and take peoples advice. Drop your nic strength, or raise your resistance, or better yet do both. If I was anywhere under 1 ohm and using anything higher than 12mg, I would be in the damn hospital, and I believe a large majority would agree with me.
You sound like my mother whom is dying from COPD. She is so scared to drop her nic strength from 18 because she is scared of having withdraws. Even though she smoked Misty Ultra Lights for 45 years, she still thinks she needs 18mg. She can't realize that 6-12mg resembles an ultra light, so she would be getting her fix with that strength around 1.5-2.0 ohms. Even if she needs to vape more than 2mg of juice a day, that is still better than smoking cigs.
Hell at 6mg on a 0.3 ohm build, I go through about 5ml a day. Not to mention I feel amazing, no more breathing treatments, no more inhalers, and no more waking up through the night gasping for a breath. I went from using my inhaler 4-5 times every day, and breathing treatments every other day, to needing NOTHING to control my asthma. And this literally happened very quickly.
Moral of the story, you need to be smart and realize what it is you need to correct. After vaping for well over a year, I would rather vape some juice that tasted like dog breath, than light up another cig. There are happy mediums that you need to find.
