I have been vaping 18mg juice for about 2 years. I vape quite often almost all day long constantly. I think I must of messed something up. I cannot feel the nicotine throat hit any more make vaping not pleasurable at all. I even went and bought some 24 mg and it was the exact same thing, didn't not have any throat it. It was like I was vaping 0mg juice. I even went out today and bought a pack of Export A Green and still nothing like I wasn't smoking at all! I cannot feel the nicotine any longer. It has been like this for nearly 3 days now. I will likely grab a cigar or something tomorrow and see what that is like. It is really weird. Any one else experienced this?
