Hi
@Liz M . Personally I think, if you are sure the vaping is relating to your migraines, using the lowest dose isn’t the best idea. If you use higher strength liquid, then you would need to vape substantially less. Since it seems very possible that it’s not nicotine causing this (assuming you used to smoke, and didn’t get migraines), and therefore some other constituent in the vapour, I think you would want to reduce the overall amount of vapour you consume, and increasing the nic strength would help with this.
