My Bad it's five levels. Starting out with a mint and going to full blast. Breeze, flurries,Chill, Frost and Artic Blast. They also have a juice called menthol ward for those that can't get enough. I don't think it is available in the express line though and maybe a custom order only.
If you are trying to quit you are probably looking for that strong top note we got used to with smoke. Ahlusion's juices are somewhat complex and generally layered. And yes, I thought people were crazy when they told me that. I still chase the strong top note a bit but now I know exactly what they meant. Also some of that stuff you don't like right now you probably will in a couple of months. If you get off the stink sticks that is. It does something to our taste buds that take a little while to recover.
I would recommend asking them about some strong top note juices that work well with menthol. The winter Wildwood is the only mentholated Tob they have but you might ask about getting some added to Desperado. From starting out it tasted the most like an old cig to me. I don't do menthol though. The W&A Sasparilla has a strong top note too. Might try it and see if they can menthol it up.
Good luck and stay with it. I worked Cigs and vape for a few months before I got clear of the smoke. Coming up on two years of smoke free. Remember too with the custom made line the juices need some time to gel or steep. Depending on the juice its usually from two weeks to a month before they hit their sweet spot.
