I did as well - Parliaments and Marlboros. I found that Halo's Menthol Ice completely satisfied that jones.I should probably try a menthol flavor because I smoked menthol cigarettes.
That said, I see you mentioned wanting something 'herbal' - Halo's Smooth 8 tastes exactly like Earl Grey Tea to me... that dry, smoky black tea, bergamot, and a very subtle floral presence in the background.
So many companies and flavors to try though...
