I've been vaping for 3 days pretty much non stop now and haven't had an analog since. I used be a bit out of breath and couldnt breath in very deep. Now that I vape, I dont feel that many health benefits yet as its only been three days, but I noticed myself yawning all the time and trying to inhale deeply but I find it very hard. Do you think its because it hasnt been long since I quit or my pv is having some kind of effects on me? How long has it been for you guys since you started feeling healthier?
