I have just started vaping as part of a plan to quit smoking. I am using a very small and basic vape88 and the lowest to no nicotine juice and only really using it in the evening. (I wasn't a heavy smoker) However after a week or so of using it I am finding I have a really crackly throat and chest especially at bedtime. It's quite an unpleasant sensation. Is this a common occurrence or does the vape thing just not suit me?
