Use the damn gray matter between your ears for more than a hat rack.
"You can do iiiitttt!!"
Okay, I don't know if that message is for me or for the OP. I see my name in it.
I received that email, "reply to watched thread", and read it before coffee. Big mistake, because it gave me a headache, but that's okay because caffeine is a vasoconstrictor and will help with the nuisance headache.
Rather than suggest that I use the gray matter between my ears, I suggest you wipe the matter from your eyes and see this troll for what it is. She has asked this same question over and over in multiple threads in this forum, while at one point saying she has a broken vape device. If she is really vaping, you'd think she could figure out for herself whether or not vaping causes headache.
Feed the trolls if you want to. I sometimes enjoy feeding the trolls. .
Here is a full safety protocol for everybody who wants to live in fear and try to take down the only truly, widely successful stop-smoking method ever known:
Don't smoke. It might kill you.
Don't vape. It might cause headache if you haven't the mental capacity or curiosity or determination to do it right and find your appropriate nic level or device or vaping frequency.
Don't drink coffee. It's a vasoconstrictor.
Don't drink alcohol. It's a vasodilator
Don't eat. Food may have fat, or sugar, or a bone to choke on, or an artificial coloring to give you cancer, or too many calories or too many carbs, or too much pesticide, or have dirt on it, or be too hot and burn your mouth, or too cold and give you an ice cream headache.
Don't drink water. It may have pollutants.
Don't drive. An automobile accident could kill you or kill someone else.
Stay in your home. If you go outdoors you might have an allergic reaction to pollen or automobile particulates, or you might catch a microbe from a human or an animal. You might slip on a wet leaf and break your neck. You might step in dog shit and mess up your shoes.
Don't have sex. It might give you a heart attack or a disease or a broken heart.
Don't read forum replies. It might cause headache.
