I had similar issues with blueberry flavor lol
not kidding
I ordered 30 ml of 12 mg blueberry and vaped it in ~6 days and that stuff was some bad experience for me as well
never had any issues with other flavors though
I had ordered 30 ml watermelon and 30 ml strawberry as well from the same vendor and these didnt cause me any problems
might be something with the flavoring and not vaping itself that causes issues...
stay away from blueberry
