I smoked for 15 years and worked at Phillip Morris so I could smoke at my desk. Yikes! I quit the day my ecig arrived but everyone is different.
DJ unfortunately it is like getting your car right
for you takes a while and will cost a bit of money. I did a lot of reading and research. I would highly recommend the
E-Cigarette Forum and I would recommend some type of variable voltage unit. Without getting too much into it it allows you make you vape hotter or cooler because if you like a lighter flavor it will probably shine at a lower voltage whereas a rich tobacco flavor like a bit more heat. The real challange is finding a flavor you like. I would look for a vape store close to you and ask for samples (they will be glad to) if not then go to somewhere like
https://freedomsmokeusa.com/ and buy a bunch of 3ml sampler packs till you find one you like.
