Between 7 and 8 hours, probably closer to 8 most days. Alarm is flexible between 08.00 and 08.30. 6- hours of sleep happens every now and then too ofc. and 9+,

Between 7 and 8 hours, probably closer to 8 most days. Alarm is flexible between 08.00 and 08.30. 6- hours of sleep happens every now and then too ofc. and 9+, not that much though. I'm usually not tired until bedtime. I can probably reduce it to 6 - 7 hours and be a bit tired half of the day. I don't drink coffee.
