I had to laugh when I saw the title of this thread. Not at the poster, but just because I have lived with chronic nosebleeds all my life, since I was less than 2 yrs old. I'm talking about ambulance-ride to the ER nosebleeds. Severe anemia, thin-lining of my nasal passages and sinuses, stuff like that and having the inside of my nose burnt repeatedly to form scar tissue 12 times, it made my life a living hell till I started to outgrow it. I still got a few when I smoked cigs, but only when the weather was cold and my house was dry-we have electric heat. I have to use a humidifier in the winter when I have one. But with this vaping, I need a humidifier and can't find one in the middle of June! Have had a few unexpected nosebleeds, woke my up actually, or just when bending over, but I'm used to it from my childhood. It's definitely the drying out of the nasal passages with the vaping ingredients, so anything that will lessen that and increase moistness is a good thing.
