Quitting smoking and ECigs (Vaping)

Happyme2009

I started vaping 2 weeks ago.... cut down my clove cigarettes for 2 weeks... mind you I was smoking a pack a day.
Today is my 3rd day without any real smokes.
My nicotine in the liquid ranges between 12ml to 8 mg, most of them.
I was a chain smoker, now I am a chain vaper.
I am eating too much too, constant hunger..... and exercising a lot trying not to gain weight....
For those who quit through vaping, did you gain weights?
thanks!
