During the last days it have been difficult to stick to the system and since I had to skip some naps it was harder to keep awake on the morning and I did few long nights during last days (means 6h night in this system).
Anyway I tried to continue the experiment and I getting used again to the schedule and mornings gets easier.
Also like Chris said, on holidays it's more difficult to keep busy and motivated. I have some DIY to do in the apartment, but I can't do noisy activities on evening and night to not disturb my neighbours and not on morning not to wake up my parents, which leave me only the afternoon and I have to fill up the other periods with other activities.
I'll keep in touch
