While unemployed I'd practice 60 hours a week and found absolutely no place at all to insert any hip drum shit with guitarists who practiced only when the band rehearsed. But I discovered the longer I played the deeper my pocket would get so I'd practice two to four hours on the day of a gig before loading up, when in days gone by I'd shuffle through the house in my slippers and bathrobe muttering in monosyallbles to any of my loved ones who dared engage me in conversation while I psyched up for a gig. I think it helped, but worst case scenario it drained off some of the insane energy anyway.
SP's comments made me think of a drummer I know who just 'thought' about his parts before he went out and played. He called it mental practice. I can't fault that, he's a lot better drummer than I am.
