Welcome to ECF
The same thing was happening to me when I first started, I quickly realised it was the sub-ohm tank I was using and was more suited to MTL vaping. So I got a MTL tank, the Zenith, and I was very happy! No more coughing or throat pain when I vape.
You are using a sub-ohm tank with your mod now so you may be better off with a MTL tank too.
Good Luck
