Chronic sleep deprivation, something that’s all too familiar as a medical student and resident.
The real solution to waking up easier is to get more sleep, but if that was the case you wouldn’t need tricks to help you awake.
Some people set multiple alarm clocks, staggered as fail-safes. Some hide their alarm clocks. However, I use one additional method that’s as old as it gets to help me wake up on mornings which are difficult.
Tip #1: Drink a glass of water before going to sleep
The urge of wanting to go pee will beat out the urge to go back to sleep… Once you’re up and in the washroom, the chances of you falling back to sleep are slim to none.
