Ahh... I hear ya man! Go get some sleep. For a long time after I got clean, if I wasn't working, I was sleeping because the cravings were just too bad.

You need to find things to do that fill your time. If you're busy doing something productive or fun, you won't think about it nearly as much.

IMO... a job is a great place to start. It makes you feel needed, important, and plus you'll get a little cash in your pocket. The better you feel mentally, the less you want to do dope.
