I've had to deal with migraines almost my whole life. I had a similar situation the first time I tried to quit tobacco cold turkey and switch to vapor instantly, but then the handful of quit attempts over the years had a similar story.
When I finally quit cigarettes (9 months running), I had vaped on and off for a little while in a transition attempt. I had increased chance of migraines for a while, but it was tolerable, mostly level 1s, no 2s or 3s (1 = pain, light sensitivity, light nausea, can still function; 2 = can't really function, but I can sleep to escape; 3 = can't even sleep, hate the world, etc.) It leveled out to normal after a while.
"Triggers" are different for everyone, but anything that throws off balance is usually an issue for me. Too much caffeine, too little caffeine... same with food, nicotine (since addiction), & sleep (getting a migraine from sleeping in too long really pisses me off.) And of course there's too much stress...
My bet is it was primarily the shock to the system of quitting and then introducing a new element. It could be the other issues mentioned as well. I haven't had any negative reaction to PG, but it's an issue with some and nicotine levels are definitely something to check.
I wish I had a more rock solid nugget of advice...
- An earlier poster mentioned water. It's the superhero of equilibrium. A reminder that vaping can dehydrate is definitely something to pass along.
- Once the initial wall is passed, I can second something another poster said... I find nicotine helps combat the migraine. With cigarettes going out into the sun was a wash (increase pain and discomfort to decrease pain and discomfort.) On the other hand, when you're in the bedroom with the lights off and you're attempting to physically shove your head through your mattress, you can still vape.
