I started vaping 18mg using VIP liquid, stopped smoking quite easily for 7 weeks but i had the most awful chest problems, worse than when i was smoking plus the liquid made me feel quite sickly. I bought some different liquid PG and VG and a lower mg one but chest seemed to stay the same, when i was inhaling i would cough and splutter. I want to try again but before i buy the stuff does vaping just not agree with some people. The other alternative is to try the nasal spray with patches but i found this much harder, bored hands probably. Any suggestions?
