Some mornings I take about 25mg of coffein (splitting up a 100mg tablet). After that I consume no caffein at all.
Sometimes when I go to sleep around 11-11.30 PM the caffein still affects my sleep, in two ways: It's a little bit harder to fall a sleep (but melatonin helps me with that).
But the thing that bothers me most is that it shortens my sleep. I would wake up earlier than usual.
In a gene test it showed that I had a slow caffein metabolism.
Why would I need caffein? Because it sharpens my concentration and I need that for school.
Any ides on how to take caffein and still be able to have a good nights sleep?
Thanks in advance
