So I've been noticing this pattern for quite a while. And it always happened.
Lately I can only sleep for 5 hours (or 6, if I was very tired). When I woke up, I still feel tired and sleepy, and could easily fall asleep again for another 1-2 hours.
But here's the thing. If I forced myself not to sleep again, I will feel kinda sleepy during the day, especially after meal. But I will be in a good mood and motivation all day.
But if I let myself sleep again, I will feel depressed and unmotivated for the rest of the day. These has happened so many times that now I'm certain of it. Overall, I feel better and more productive on a 5-6 hours sleep.
Anyone know what is happening? And how could I get enough sleep while still have good mood and motivation?
I took piracetam in the past for about 15 months on and off. On piracetam, this problem is worst. I woke up after 4 hours sleep. If I let myself sleep again, my mood is even worst. I don't know whether this problem has existed before piracetam. I only start noticing it during my time on piracetam. I've stopped piracetam for about a month.
