I have had my DSE-901 for a little over 2 weeks. I have been truly enjoying my e-cig, but in the last couple of days I have been getting a much harsher hit & not as good of flavor. I made sure that my batteries were fully charged, have been maintaining my atomizer & actually washed/boiled it last night, I also cleaned my cartridge & the "wick" that hold the juice last night. I am still, however, getting the harsher hit & flavor. What have I missed, or what else should I try???
