I have some experience quitting vaping, in fact I was the one who petitioned to have that Quitting Vaping section added to ECF...You can read my quitting story in there
I quit for a little bit more than a month actually, and while I was slightly disappointed that I ended up going back to vaping, there is still some good that came out of it; I used to vape 24mg of all sorts of juices and now I vape 6mg of unflavored juice.
I recently tried quitting again by vaping no-nicotine juice, and in retrospect I feel that it was a mistake. I was more frustrated about vaping with no throat hit than I was about nicotine withdrawal. Trust me there's nothing out there that will even remotely resemble the TH that nicotine gives, Flash by FlavorArt is trash, peppers, menthol, cinnamon etc, I tried them all and it's not the same.
The next time I quit, I'm not going to bother with weaning down the strength because in my opinion if you're addicted to nicotine, you're addicted, regardless of the strength and if you lower you'll end up compensating by vaping more. Instead I would try gradually weaning myself off vaping period - not vaping for 2-3 hours after waking up, not vaping after meals, not bringing my e-cig to the grocery store etc. I think that after a while of challenging yourself to not vape for extended periods of time you'll realize that you really don't need the crutch and eventually you'll be able to go a full day without it, and then 2 days, and then a week and before you know it all your stuff will end up in the BST.
My final piece of advice would be to clear out your vaping supplies - no sense in keeping the temptation lying around. Maybe keep an eGo Twist and a few cartos in a drawer in case you fear a relapse and to avoid going back to smoking.
Good luck my friend and keep us posted on your progress!
