“do it for about two weeks and then at that point once you're free from the detox and the withdrawal now you're in a somewhat naive state where you're taking your caffeine on I'm telling you to stop caffeine you're taking it on at 11:00 after you've woken up let's say 7:00 in the morning at that point we've now got this nice Clear Window that has been consistently happening between 7 to 11: in the morning and I'm going to ask you now do you feel rested restored and refreshed and can you operate with cognitive acumen and skill in those first morning hours”
