then there is deciding which juice you want but with thousands to chose from its a case of trial and error finding ones that you will like.
firstly how many did you smoke for and for how many years.
there are 2 main juice types.
freebase nicotine will have more of a throat hit like a cig and can come in 3,6,9,12,18mg strength.
or salts which are much smoother on the throat and only come in 20mg,10mg and now i believe 5mg.
i smoked 20-30 a day for 37 years and gave up overnight with 18mg freebase 9 years ago. after a month i was down to 3mg and have stuck there ever since but i chain vape and am chugging away all day every day.
i didnt like salts as 5-10 puffs and my head was light headed so nic od.
once a decent kit is decided on then others can advise on which juice to try.
what sorts of flavours are you thinking of trying as the world is now your oyster and you dont have to stick to backy flavours but if you do there are some great ones infused with fruits and nuts that are worth a try from manabush nokomis range (above link 2nd link)
