Lemmy spent much of 2013 struggling with diabetes and related problems which led to periods in hospital, postponed tours and even a rumour that he'd died after cutting short his comeback appearance at Wacken in August.

"[Lemmy's] been up and down," Singerman tells Decibel (via Blabbermouth). "He's got a really bad diabetic problem, and it changes on a daily basis. A lot of it is just fighting the bad habits, the things that he's not supposed to do anymore. He's stopped smoking, but he probably sneaks Jack and Coke here and there. He'd be lying to you if he said he stopped. He's been trying to substitute it with wine, and I'm sure he's slowed down on the speed. He thinks wine's better than Jack, but it's still got tons of sugar, you know? He doesn't grasp that he's just trading one demon for the other.
