Drink lots and lots of fluids. If I'm vaping, I'm sipping on something. Experiment a little with some lemon or other flavorings for water. I'm surprised to find that I like lemon water, something I would never drink with a cig.
It also helps to slow the draw way, way down. Doing so helps wicking time and helps prevent hot air in the vapor stream. Take notice that in most videos, the reviewer takes forever and a day for a single puff. It's an easy habit to get into, and really worthwhile imo. At it's extreme, a starved coil will produce a vape that tastes horrible and may actually hurt the back of your throat. My theory is that slow wicking is the culprid behind many of the 'tastes burnt' complaints.
Like southernIL, I also find that I personally have to watch the amount of alcohol in my juice. I have a berry flavor that I can only vape for a few hours until I need to switch to something else.
Just experiment, and, hopefully, you'll soon come up with what works for you. Good luck, and happy vaping.
