+1 to what the Gents above have said. Do you like desserts? Do you like fruits? Do you like tobaccos?
I started with small bottles of various flavors. I was able to find a B&M that had a tasting bar. Finally started DIY last summer so I could make what I want when I want. Mt. Baker Vapor has sampler packs and decent prices for 15mL bottles. Give yourself time to try things. What you like right now may not be what you like in a month or two or three, especially if you've recently quit smoking and your taste buds start to heal and refresh...
