It is almost like it is the study that they did on the conventional dosing regime FIRST beofre they then did the study into circadian rythyms. Was that the one that you meant to send? Lol! I thought it was a bit strange! Still you learn heaps reading all these papers! If you have sent me the wrong one can you send the other. Ta muchly. /(^..~)
