Sorry you've had so much problems!
Welcome and congrats on quitting the smokes.
My favorite and easiest set up is MVP 2.0 and a Kanger V2 w/a sub ohm coil 0.8 ohm have several actually.(have the Mega with the sub ohm coil, that and the V2 are the closest thing I've found without using a rebuildable, they are juice sucking monsters though, not as much as a Kayfun, but approaching, it but great vapor and taste)
I'm a fruity /desserty in tastes too. Mother's Milk by Suicide Bunny universally is loved by friends that ask about vaping stopping smoking (vaping it right now)
I have about six flavors in tanks ready to go at a whim of craving ...Queenside by Five Pawn, orange & sweet cream, with coffee vape. Scouts Honor, 7th & Grand, green apples. Mangrila, Alice & Vapeland, mango goodness, Frankenvape by The Standard, another all day vape I love, kiwi marshmallow (yeah I know rigth? but it's good) Mother's Milk, I love it what can I say, strawberries & cream yum, I keep a tank of Hoops, Alpha Vape, melon goodness, and some DIY Blueberry Icecream. (and one with Claim Your Throne, Ed's fave, Butterscotchy goodness.)
Your tastes will evolve so unless you just LOVE LOVE LOVE it crave it stuff..stick to the 15 and 30 ml bottles, or you end up with a flavor graveyard, which we end up trading back and forth with friends/family that vape..so no losses. And you find new stuff you love that way. Taste at local B&M I had a craving for Vaping Rabbit's White Rabbit (blueberry shortcake with lemon and darn it they're all out as is their website, so I'll have to wait)*lol*
find what's best for YOU, see if the folks at a vape shop or others in your area will let you try out their gear, I found they're more than willing and eager to do so...
good luck!
