Welcome Brooder,
Congrats on the quit thus far, this is by no means a easy task if it were there would be no nicotine addicts. It's common to have a difficult time sleeping in the early stages of your quit. Try melatonin pills, some people (me) swear by them, others can't stand em. As for alternatives there are many types of fake dip out there, some will be easier to find, some will imitate dip better than others, but if you're craving there are many other things you can shove in your dip to help you beat your cave: coffee grinds, tea bags, atomic fireballs, seeds, any hard candy, etc. You should start feeling better after three days or so.
Some advice: Get involved, don't just post roll and run...you have to reach out and connect with your fellow quitters. Above all else what keeps me quit is the fact that every day I promise my fellow quitters/friends/brothers that I will not use nicotine. I post roll with them, live chat with them, text them, facebook with them, etc. I had to put some time and effort into getting to know my fellow quitters and so will you. Read/post as much as you can, live chat should be your new home for the next couple weeks/months/years, start a Sept 14 text group, etc...
Quitting with you today Jason, send me a PM if you need a number or just want to chat.
Mike aka MCO
