iMac wakes from sleep after 10.8.2 update

Never had this issue in 10.8.1, but have been noticing my iMac waking from sleep in the middle of the night. It is quite frustrating as I have my iMac in my bedroom and the brightness of the screen seems to wake me. Anyone know of any fix for this? Thanks ahead.

A few things to try:
Repair disk permissions
In Sys Prefs>Energy Saver, make sure the "wake for network access" is unchecked
In Sys Prefs>Bluetooth>Advanced, make sure you have "Allow Bluetooth devices to wake this computer" unchecked.
Reset the SMC (http://support.apple.com/kb/HT3964)

Hopefully it's something as simple as that, if not then either there's a new bug in 10.8.2 or there's a poltergeist trying to check their email in the middle of the night on your iMac.

Will definitely give these a try. Thank you!

Also, I seriously hope there is not some poltergeist trying to check their email in the middle of the night! Ha.

Check this thread as well - I have been facing some wake-from-sleep issues, but after a SMC reset things seem better...at least for now.
