Bugger, time to move on I guess. I wonder why he left the band?
I believe that unlike him, the rest of the band couldn't go on at the same pace as before the death of Paul Gray, and this frustrated him. When Corey Taylor announced he was unsure of whether or not the band would even continue making music at all, Jordison responded by saying the band would go on with or without Corey Taylor. I'm guessing the rest of the band weren't with him on that one, and he would later decide to part ways with them.
I think hes off the drugs which caused him his weight gain.
