Can you describe the feeling your getting from the TH? It's hard to give you any real useful advice if we don't know what the problem equates to. Is it burning, Hot, non existent, gagging, ect? This will help determine where to direct you better. You do have to remember that even though it's water vapor you still can get that reflex feeling in your throat kind of like when you first started to smoke. If your continuously trying to adjust you might not dial in the TH, flavor or vapor production you want. Nic level has a bit to do with this equation as well so hopefully we can get you in the right direction.
