Dude, just do what you need to do to feel better.
Honestly, if you trained yourself to DL, you can train yourself back.
I still think it would be wise to go on the vape elimination diet and DIY ESPECIALLY if you want to keep vaping. Maybe it's flavors, maybe it's you WHO KNOWS.
But, the lamenting.... No one is in your shoes, no one is feeling your symptoms. I think the idea of no flavor MTL vaping is probably good for you. That would treat the hand to mouth AND the nic issue. But, I am getting the sense that is not what you WANT.
With the right flavorings for all you know (or none) DL would be a breeze.
But, unless you proceed in an investigatory fashion I very much doubt you will have the chance to do so, if you are in the US, and if you are like, wanting to vape other than menthol or tobacco.
Single flavor mixes to start. Less flavor. Considerably less. And I for SURE hope you do all this with your doc's approval.
