i started vaping 2 weeks ago with the aspire mini and at first I thought it was great. Into the second week I started getting a really dry,sore mouth and sore throat. I researched on the Internet and found its common when vaping and that I should drink plenty of water. I have always drank loads of water and have been drinking even more since vaping. I tried different pg/vg ratios and still nothing worked. I was getting really annoyed to the point where I thought About quitting vaping. I decided to try another tank and I bought the subtank mini first one I bought was broken so sent it back and received my replacement today. I started vaping on it with the same juice I had in the aspire mini and noticed my dry mouth was disappearing, I have been on it all day and I have no dry mouth. Anyone no why the aspire mini is giving me a dry mouth and the subtank mini isn't and if anyone else has had this problem. Thanks
