So I'm still having throat irritation after what's now 17 days into vaping. Here's my issue though. I started on 100% VG, caused irritation. I tried some new flavors from my local brick and mortar, with different PG/VG ratios, still having throat irritation. The thing is, when I first started I was using disposable Blu's, no irritation. I still have one left over that I take a hit off of every now and then, no irritation. And by irritation I mean it's pretty much instant. As soon as I take my first hit, it's there. Now if I wait about 10-20 minutes, it goes away, but comes right back on the first hit. When I tried flavors at the brick and mortar, they used the dripping method on a cigalike sized batt, nice and smooth with no irritation. I'm using the 900mAh 3.7v regulated X2 with a matching X2 clearomizer. It's a top coil, so I just ordered some bottom coil nanos from SI to see if that fixes it. The only other thing I can think of is that my body doesn't like VG. Any other recommendations?
