Noticed l-theanine does not dissolve in my green teas like sarcosine does. It just floats around in little clumps. I added milk to it and stirred it around, that seemed to work.
I don't know if it clumps up in only water, but in green tea it clumps. So, just fyi, it might not dissolve in certain liquids.
Took it last night. Had a restful sleep. My smartwatch put me at about 5 hours of 96% effective sleep (it calculates "restlessness" and light sleep versus heavy sleep). My positive symptoms, which were sky high on the weekend, decreased. I am not having intense delusions or fears of car accidents anymore. That could be because my pneumonia-associated fever finally broke and disappeared and I recovered physically, or just the l-theanine working after a couple of nights.
Either way, going to keep taking this. With milk.
