Caffeine takes 30 minutes after ingestion to enter your bloodstream and have an effect on your concentration.
The caffeine nap: Chug some caffeine before a nap. You will wake up naturally 20-30m later once the caffeine kicks in. Wake up with a huge boost of energy and perhaps a mild euphoria.
Set an alarm as backup. Limit the nap to 25 minutes so that you don’t enter deep sleep.
