I have to change my atomizer daily because it starts tasting burnt and burns my throat a little bit. I do take many large puffs per day. But on the atomizer box it reads, "Change the atomizer about every two weeks, about 500 puffs/day". I don't believe I go much above that. Please advise on what the issue could be. Every person at each store I go to gives me a different reason why this is happening. I'm fed up, so I thought I'd ask the experts instead of the wanna be's. Please help!
