Put a little PG or VG in a bowl, and volume will actually increase. I used sugar free
throat lozenges as well.
Try that before resorting to ditching all your
e-liquid and spending tons of money on new liquid. You can also pick up an inexpensive bottle of PG in your local craft store or Walmart and add a few drops to you liquid. Not too much or you'll reduce flavoring and nicotine content.
