How to uninstall and remove cyanogen mod 10 for the samsung galaxy s3?

Help, i just installed and flash the cyanogenmod 10 jelly bean 4.1.1 for my galaxy s3. But i wanted to return to touchwiz. How do i reverse this?

Answer: 
1.) Reboot into recovery and restore a nandroid backup. 2.) (if you did not make a backup before flashing) go to your local xda-developers.com and find your phone and download a touchwiz or a stock rom and then boot into recovery and flash that. 3.) if you need me to walk you through the process, PM me in xda-developers, i'm wolfbeef123 thanks
