Hula definitely makes some great suggestions...so I'll second those comments.
In addition..I was wondering if you have been off of cigarettes for 2 months as well? (some people have some transition time where they are still smoking a bit as well). Your tastebuds will change dramatically the first month or so after being done with the cigarettes...I have juices I couldn't taste at all back then, or absolutely hated, that I love now. Not to mention, the juices will change as they steep and mature as well.
Unfortunately, what you are going through isn't all that uncommon. I think some of the tobacco's Hula suggested are great (even though I am not a tobacco vaper anymore)....teas are a pleasant surprise as well. They weren't something I ever would have thought of when I started vaping...but once I tried a few good ones...WOW!. Very nice, very real (if you get the right ones) tasting teas. Some of my personal favorites have been green peach tea, berry tea, and green pear tea from Rawr. Ahlusion is also supposed to have some amazing teas....I will be trying them in a week or so.
You mentioned Boge cartos....since you are using a Twist, I might suggest grabbing a Vivi Nova. With some of the recent issues with Boge cartos, a lot of people also report an odd taste..and in some cases, some people are led to believe its the juices when they are trying out new flavors, when it could be an issue with the cartos. I'd maybe try some of these juices through another method just in case. I personally am loving the vivi novas...SUPER easy to use, great vape, consistent performance, no muted flavor since there is no filler material....and a really, cost effective solution as well.
What is the flavor of the one you do like? Have there been any other specific flavors you "almost" like? Or maybe even flavors you know you like in the non-vaping context? That might help us give you some more specific flavor suggestions...
There is definitely a lot of trial and error early on....and steeping can make a world of difference, so if you tried juices straight out of the mailbox and think you hated them....give them another shot in a week or two. Hula suggested a lot of great vendors, so if you haven't tried some of those...I'd suggest grabbing some sample packs from a few of them as well. The sample sizes are definitely the way to go to start.
Best of luck...it will definitely get better!
