Jones revealed the news in an interview with Metal Hammer. He told them, "Finding out you're diabetic is pretty dramatic. I just started feeling weird, and then I started getting really clumsy. I fell down some stars and broke a finger, then fell down some other stairs and broke a toe. Then I collapsed.

"I was in a coma for three days. They basically told me I had the highest sugar level they'd ever seen. Afterwards, they told me I had a 50/50 chance of coming out with brain damage."

In January of 2012 Jones issued a statement about his reasons for leaving Killswitch Engage and touched on the illness, "Well, I guess I will shed a little light without going too deep. As some of you may know, I've had a pretty interesting couple of years to say the least battling with some personal issues. One of the low points being diagnosed with type 2 diabetes that went unchecked for years. The rest of the band stuck with me through it, and to be honest they are the ones that kept me going. The whole experience definitely put a scare in me." Read the rest here.
