I would toss the ashtray.  For me, it's smell will trigger smoking.
I just carried my APV around the first week or so.  Then I would carry it around and sit it just out of my line of sight.  Let the urges tell you when.
If urges are often, add an extra 1-2 draws for satisfaction.  I would start with 24mg 
juice that is minty.  My tasttebuds were shot, so I could taste soft flavors.  If the 24 is too weak, your urges will say 
vape more.
On my nightstand is a coffee mug for my APV...my APV is never far.
Just go by urges for 2-3 weeks.
