Am glad more ideas are coming about. So many things it could be.
For me, I got frustrated with store-bought juices. I later came to just accept that my tastebuds, whatever their condition, were the boss as to taste. It did take me a lot longer from the point of my last cig to where I fully tasted a juice.
Juices that I tried early on, I had to go back to later on to see if they were worth anything, taste wise. In the end, I did find some, but I got my greatest satisfaction with DIY. But, until I got my taste back, I just muddled through and stayed off of cigs. That is really my overall intention.
I have to say that I do not know of any tobacco flavors. I really don't want any reminders and I am not sure I would be able to replicate a cig taste anyway. The tobacco companies put a lot of chemicals/ingredients into cigs to keep me hooked, I want no reminders.
Good luck finding your path.
