Hi there and welcome to the Planet
1st things 1st, Eliquid will never taste like a cig, you can get close, but more or less, the juice ends up tasting like fresh unburnt tobacco. Other members here who prefer tobacco flavours can point you to the better of them.
If you really want to do this, best advice I can give you is to get a few 900mah or higher Ego Style batteries and some Vision Clearomisers. The clearo's are the best for faff free.
Think about what else you want out of Vaping. Alot of members come into this looking to quit, but end up picking up a hobby. In the end it still saves you money, but start up prices can be kind of scary. A good Ego starter kid, costs as much as a carton on cigs and pays for itself in just a week or two depending on how much you smoked.
How much do you smoke NOW? If you are a heavier smoker, you will want a higher MG of nicotine, 24 or 36 is where most people start, then they lower the MG the longer they vape. We have a few ecig users now who are going to 0 nic or are all ready on 0 nic
Keep in mind, for roughly the first 12 weeks after you quit, your body is going to give you all kinds of shit to make you THINK you need a cig. Check out this thread for 1st hand user accounts of side effects.
http://www.planetofthevapes.co.uk/forums/showthread.php/1075-Side-effects-of-vaping The most side effects you will experience, will be from actually quitting, not taking up vaping.
Your taste buds will also play up on you, BIG TIME. For days it will seem like everything tastes like cat poo, then suddenly, every tastes 1000 times better than you remember. Fave foods, suddenly become overpowering and things you thought you didnt like before, taste brilliant.
It's a lot of information to take in at once and its a whole new language, but never be worried or nervous about asking a question, no matter how silly or stupid you may think it is. We were all there once
