wow!
@Cozy has near enough answered it all for you above. well done fella.
now i cant help with any of those kits hes mentioned but i think they will be prefect for you as they have variable wattage so you can turn up/down depending on the coil you have in the kit unlike the kit you already have which is a fixed 40w direct to lung output and a bit too much for a beginner on higher nicotine.
what i will say though is coughing is part of the detox and you will cough now and again for anything upto 2 weeks but this is only while vaping. if you are still smoking the odd one here and there it puts you back at the beginning.
coughing is literally your body trying to heal itself and kicking the shite out of your lungs and is a normal part of the healing process. sadly vaping is not a miracle cure and if damage is already done by smoking then it wont cure that but it will stop it getting any worse as its 95% safer than smoking.
the initial outlay will hurt your pocket for a while and it took me a year before i was in profit. i did go overboard though and spent a few grand on many kits and as much juice as i could. my theiry was if i spend loads then it will be an incentive to look at all that i had spent on gear and know that if i had just one cig i would be back on them again and i would of wasted all that money. worked for me as gave up overnight after a 37 year of 20-30 a day and not smoked a single cig in over 5 years. a good reminder just to see how much ive saved is in my sig below but if your using your phone you cant see it so have a look here as 18 grand saving on what i would of spent on cigs is a win win in my book.
