IF you can, a trip to doc might be in order. I went to my doc and told him the exciting news that I had quit smoking and started vaping! I took my pv with me. And was prepared to explain what " vaping" was. He had TONS of questions!! He was also well aware of the unpleasant things the body goes thru when it is sans cigarettes{bronchitis, canker sores,etc} He prescribed some magic mouth wash with a shot of steroids to ward of anything more serious . And boy did it HELP! I have an amazing doctor though....unfortunately they are not all created equally. He was very excited that I had put the analogs down.
You could always print some info off the interweb...take it in to ur doc. There's no reason to suffer if you don't have to, but If going to doc is not an option...I've read a bunch of good ideas already posted ....humidifier...steam from hot water from stove....hot steamy shower,u don't have to get in if you dont want to, just sit in there....maybe some vasoline in the nose ....ummmm, trying to think....and oh! DRINK! Vaping WILL dry you out...bad! I thought I was getting sick when I started vaping...and I would go drink a Hugh glass of water and then feel fine. You'll realize how important it is to increase your WATER intake when you see how much better you feel when you do drink.
Anywho...this too shall pass! Vaping is worth it! Hang in there! Happy vaping!
