Welcome @Icandothis2 you are making a decision that will change your life for sure, congrats and you have come to the right place for support. I did not use NRT's, but I had some at the ready.
The Nicotine is gone from your body in about three days, so I figured if I made it 3 days the physical symptoms would be over and from then on just have to deal with the mental part of the addiction, so far it worked for me.
I would also recommend Allen Carrs book, (The Easy Way) it was a big help to me in understanding the addiction.
