Hi godspeed1208, I can share my 3 weeks vaping experience with you, but it is purely my own experience. As I found out here, everyone has a slightly different experience.
Yes, with the big puff of vapor coming out of your mouth, it definitely feels like smoking, but to me it feel like having one of those ultra light cigarette. Which make you feel like not having enough and need to light another "one", so therefore may lead to "chain vaping".
At my stage, I haven't nailed down what is suitable for me.
What e-liquid PV/VG% or whether pure PG or VG?
You can read my earlier post, I am having very bad headache from 2 of the flavors I got.
I found out that it can be due to a lot of reasons, your reaction to PG, nic level, certain flavors or you are simply not having enough water.
Yes, when you vape, you need to drink like a Fish. It will dry you up!!!

All these might sound negative to you or to some other members but it is just what I am experiencing now.
Now, on a more Positive note,
Yes, it can definitely replace smoking, because even with my headache, I haven't light a cigarette since I started vaping.
I started looking at vaping when I saw someone holding this "electronic pipe" to his mouth and blew out a puff of "smoke" about 3 months ago. For the next few months, I did my research on the internet and come across this forum. I didn't join in to post because I was just a smoker then.
So, gaining more knowledge on PV and some understanding of our country stupid regulation, I devise a plan to order and bring in my kit and juice, at the best I can. I am Solo all the way knowing that help from others may be difficult to find or offered.
Now I am vaping a cloud while replying you.

To sum up my grandmother story, It will work if you want it to work. Look more to the positive (overall health) and less of the negative (so much trouble for something that is not 100% like smoking, "
applies to people from Singapore only")
There is a lot of obstacles for people like us in Singapore and more will come.
For me now, to make this sustainable I can't go on as a Solo, so I start posting here and make new friends like you.
Help will come, just have to be patience.
ECF is all about extending help to fellow vaper, new or old. but of cos, still need time to get to know you better.
Cheers
