So after trying 2 different e cigs that didn't work ( in that they weren't powerful enough to make me stop smoking fags), I've finally found one powerful enough that successfully replicates actual smoking! It's an eleaf istick. It has a powerful battery and I get a really good drag from it without having to drag so hard. I was finding the ones I had before were unsatisfying and so I was still smoking. After a horrid chest infection and bad cough the last 2 weeks ( which I smoked through throughout ), I decided enough was enough and I had to get an e cig that would do the business. And it's worked! Not had a fag for 2 days now and I'm very happy with this one. Am so relieved and just wanted to share the good news!
