Hi Zenith,
Huge congratulations on your quit to date, that's a brilliant start, seriously impressive getting through that on your own.
It is inevitable there will be ups and downs along the way, so I echo what's been said around reading and educating. We are a friendly bunch and it will be great to have you join in.
Just a couple of things, I echo what Doreen said about Nope, it has helped me through a number of tough days. It is a commitment to not have a puff for the next 24 hours. Do that and repeat, it will look after you. The other thing is be really kind to yourself. Treat yourself at the milestones, doesn't have to be big, just something you do for yourself that you may not have done when smoking. Be forgiving of yourself as well, you'll have ups and downs but don't judge yourself on the irritable moments, you are doing the best thing for you, loved ones and friends.
Look forward to seeing you around.
