I wanted to share my experience with using sweeter e-liquids. I’ve been vaping for a while and usually stick to fruit flavors, which lasted me about a month without any issues. Recently, I decided to switch to a dessert-flavored juice, and I noticed my new pod burned out way quicker than the others. 
I was getting tight draws, and burnt coil after just a day, and a noticeable burnt taste made the whole experience unpleasant! The only thing I changed was the flavor, so I’m starting to think the sweetness is the culprit. Has anyone else had similar issues with sweet flavors? 
I used to stick with fruity flavors without any issues, but when I switched to a dessert flavor, I had the same problem—burnt coils and tight draws in no time.
To try and make them last longer, I’ve found that cranking up the wattage a bit or letting the coil soak longer before hitting it can help.
Sweet flavors, especially dessert ones, tend to have more sweeteners like sucralose, which can caramelize on your coil and cause it to burn out faster. I’ve noticed the same thing when I switch from fruity or menthol flavors to desserts.
