I know how you feel I was the same way when I started. First all I wanted was tobacco flavors, realized majority of them arnt good, and hated the really sweet flavors.(I still dont like them)
Look for vendors that let you pick your OWN flavors for sample packs.
I like BlueMist Vapor. Prices are good and you can pick your own. Plus they have 250+ juices and you can add extra flavor shot if youd like.
For tobacco flavors, vaperite has some pretty good ones and backwoodbrew is also popular for tobacco flavors, but personally I didnt think they were that great, but thats me, others love them.
The first juice I found that I liked, and was able to vape for more than a few minutes, was black&mild from CCV. I got it for free with my E-Power and to this day its still one of my favorites. Its a tobacco flavor and has just a slight sweetness. I dont think it tastes like a black&mild but its good neway. Has a nice mellow maple-like flavor. Id maybe give it a try, especially since CCV has free shipping so all youd have to pay for is just the juice.
I dont know if you like coffee type flavors but I found that a bunch of them are pretty good. If you get the right ones their not overly sweet and have just a good flavor. I really like the Cafe Caramel from BlueMist, so much I just got a 180ml bottle. Has a nice suddle coffee taste and a creamylike caramel flavor, thats not overly sweet at all.
Those have seemed to work for me, but obviously might not for you. I def know how you feel tho.
Dont give up bc you will find something you like. I felt the same way you do at first bc I couldnt find anything I liked.
Get some sample packs, no flavors too crazy, and youll find something.
Goodluck with it!
