Schrock: I'm sure that's been tried, but one of the new things they found is this specific tie between the circadian rhythm in our bodies and drug addiction and they found that it is actually through an epigenetic modification of the circadian rhythm; so our circadian rhythms are reset by these drugs; we actually crave them at certain times of day and that is contributing to the necessity to, you know, relapse and go back on drugs or to get that craving, you know, at a certain point.
