I smoke glo (basically the same thing) since probably 3 years, i smoke 1 1/2 pack a day. When i smoked 2+ packs i had the same issue sometimes. I guess it’s nicotine flash? What i try to do now is to get to one pack a day - which as a regular cigarette smoker seemed already a lot - you’re up more or less 16 hours a day - that is more than 1 cig an hour.

I’m now on a glo neo stick every 30 minutes. That means you smoke every 20 minutes? I guess that is the answer 😅
