As I consider the idea I'm not entirely sure what turning only to the Holy Spirit would look like. I imagine it means serious Bible reading and prayer. Of course then you are looking to other sources than the Holy Spirit -- the aforementioned Bible and prayer.
My point is simply that embracing sleep, or music, or beer, or sex, or exercise, or nature, or books, or food as a good means of refreshment is right, as long as it is done with faith in God as the ultimate source of such things, and as long as the things are not abused or substituted for a hearty seeking of the Lord. This is not an either/or matter. Leaning upon the Holy Spirit is not contradictory to a good night's rest or exhausting exercise. What I suggest is an hour or two in the Word and prayer while sipping a Sam Adam's Winter Lager and listening to Todd Agnew's Christmas album play quietly in the background, for example.
