quitting smoking (need advice)

[m0de]

title.

basically i have been smoking for 7 years. im less than a month away from being 27, and i have been smoking since i was 21. im thinking about going with an e-cigarette, and the gum. i priced around for an e-cig kit, and found that the average price for a starter kit from several different retailers that have good reviews is around 60-80$. im thinking about getting this one that has 10 cartridges, 2 batteries, wall + usb charger for 80$

any other advice from those who have quit?
