Next to throat hit, flavor is the worst thing to get right about vaping since it is so subjective. I had my taste buds go wacky after about the first month of vaping, nothing tasted good. It went back to normal, but happened a few times (new taste buds growing? Who knows!). Hang in there, change flavors and come back to your old flavors later.
I seek out strong flavored e-liquids (TastyVapor, Halo, FlavourArts DIY) and don't seem to have issues with flavors. It takes a while to find good flavors that you'll enjoy (try to find new flavors in small amounts on the Classifieds to save some money). Purchasing FlavourArts (or other extract flavorings) can give you some control to fix up weak flavored liquids yourself. I find most stock Chinese liquids to be fairly weak flavored.
My go to best flavor and throat hit is my 510 and Menthol liquid which seemed to really help get me over the cigarette hump. I started to use menthol liquids when I wanted a good throat hit (though never smoked menthol cigarettes!) and also higher nicotine in that menthol liquid for when I needed a cigarette. A higher nicotine takes care of the craving and also will give a bit more throat hit (I used 24mg for cravings). I'd vape the higher menthol when I wanted a cigarette and switch off to another flavor to just vape for fun and relaxation. You don't mention what mg you are using, but do know that if you reduce it too quickly, you can have problems (been there, done that!). Don's method of chain vaping low and hitting a high mg liquid when you want a cigarette is spot on.
Menthol drops are easy to make with Pure Grain Alcohol (purchased at a liquor store or grocery store and usually found under the name EverClear). A good recipe that I've used can be found on this thread

Menthol crystals can be purchased on eBay from Gumby96
gumby96 items - Get great deals on menthol, Health Beauty items on eBay.com! You can add the menthol drops to many different flavors including tobacco and fruit flavors to boos them a bit. Again, experiment in small batches.
If you know you just won't like menthol, you can try to add throat hit with anything acidic. Try a bit of the PGA, high proof Vodka, Rose's Lemon Juice, vinegar or citric acid. Experiment with very small batches of liquid so you don't waste much!
