Hey guys, i just recently started filling my own cartomizers instead of buying pre-filled carto's. It has only been a couple of days and im running into some problems. Im using old carto's which were the same flavor my eliquid is and i cleaned them out. After i drip about 15 drops into the carto it vapes great for a while but they run empty VERY quickly, after only about 3 hrs of moderate to heavy vaping. Any help or tips would be greatly appreciated.
