Yeah I do have good sleep.
I even tried 100mg L-theanine for 2 days ago, but I'm not sure I felt any effect of it, not what I noticed. And well, I'd somewhat dream (though not vivid or big). But sadly I forgot it before I was able to write it down ><

I use to go bed between 00-03
But I will start go bed around 11pm - 00. 1am as latest. (tomorro have to wake up around 7-8am, so going bed today maybe around 10:00pm - 11:30pm)
I use to sleep probably about 7-10 hours a day.

Thanks for link, I will check it out.
