Welcome my friend. Nice decision, nice place to get help Wish you luck and all that. Sttill;
You dont need luck with e-cigs You need right liquid with right device. Mind you? Every device is right at that. One prefers this other prefers that. But the right liquid changes according to individual tastes and if you are allergic try to get less PG. Count your nic intake and have a high nic level. You can always dilute them adding Vegetable glycerin.
Get a dual kit. You need 2 batteries at least 2 clearos will not be bad and replacable
coils so that you can change them and clean and reuse them (Later change the coil and wick etc)
Dont give up You will find appropriate set of all in your short journey. Dont fight with stinkies. Some leave them aside and never smoke after first intake others smoke once in a while but at last you quit. I am sure if you find right liquid You can not smoke your old cigrettes. Because they are not what they used to be before.
Go to it my friend you are in winners club now.
