Dee. Welcome
Without going into too much detail, I would suggest you look into a different type of e-cigarette as soon as possible.
Nicolites are expensive and rubbish. I used E-Lites and thought they would work for me. They didn't work though and I had Nicotine cravings, mood swings, and never got even close to stopping smoking with them.
They might work for you, but don't expect the road to be easy... what they claim to offer the user is
lies, made up to sell you a product. Each refill says it does 200 puffs, but that's not 20 cigarettes in NICOTINE, so unless you were a light smoker, you might hit a brick wall soon.
IF that happens, please, please do not do what I did and buy more and more batteries and refills. That is not the answer. All the supermarket e-cigs (E-Lites, 10 motives, Nicolites, Vuse, Vype, Njoy) are all unnecessarily expensive to run and won't work for anything but the lightest of smokers.
I don't expect you to believe me, and that suits me fine, because if you run into trouble a few days/weeks down the line and start asking "why am I still craving cigarettes and why do I feel so terrible" then you'll remember my post.
