Welcome Tex,
Read, read, read and read anything and everything on this site!
Get over to the May 2015 quit group and start posting roll every day (early too, people get pissed when you commit not to use at the end of the day).
Get a hold of some numbers the text or call when you're feeling weak. PM me and i'll give you my number.
Remember - this is about you quitting this crap. We can help and support, but you have to have your mind right. There is no try, just do it one day at a time.
Finally - technically, tomorrow is your day 1, you've used nic today. Power through it, post roll tomorrow morning.
There are a bunch of great people here for you to lean on. Use it.
