I have realised since getting back into a routine of going to bed early and getting up early I don't consume nearly as much caffeine as I used to consume. I guess my body is just used to getting up and staying up without needing caffeine to keep me awake. I just finished the census and I thought it was going to take way longer than it did. I am currently waiting for the dishwasher to finish it's cycle and then I will go have a shower then I will cook/eat dinner and go to bed.
