I just got some new flavors in the mail and wanted to try them out. I've been dripping lately, so I took off my atty, blew it out really well, several times until there were no more drips. I added my new flavor, took a puff and it was a terrible burned taste. This is NOT a new atty with whatever residue is common with the new ones. It has been fine all day and was perfect with the last puff I took, seconds before I blew it out. Any ideas?
