Awesome decision to start early. You can do it. We will help you. And you will help us. We're all in it together. 2 years ago I was in same position as you. It is the best thing you will ever do.
I still use the fake stuff too. Do whatever you need to stay away from the nic. For a while it seems same, but over time it eases up, you wont freak out over not having any with you, will be able to go days without even thinking of it, etc. For now use it to break the chemical addiction, work on the physical part later.
Happy New Year. Shout if you need anything.
