Hi Tammy, unfortunately what you are going through is normal for where you are at in your quit. Just power through it, use an air cigarette if worse comes to worse. That's just getting a cut straw, pen or even just pretending you're holding a cigarette, then go through the motions of "smoking" it. It worked REALLY good for me and others at tricking our minds into thinking it was getting the real thing.
Unfortunately for the insomnia, you'll either need to go through it as it's only temporary or use a mild over the counter sleep aid temporarily to help you fall to sleep. I found using one nighttime Bayer a couple times a week was enough to allow me some sleep
