I was noticing I was getting a significant decrease in vapor production and thought i might need to change the atomizer, so I did and it isn't working properly now. I get an unpleasant taste and still hardly any vapor production. I have tried 2 new atomizers still with the same issue. I even tried switching back to the old atomizer and still the same issue... unpleasant taste and hardly any vapor production. Help would be appreciated. Thank you.
