Had high hopes that this supplement could take the edge off at night, but after 2 weeks varying the dose from one cap to six i felt none of the marketed effects.

Have not really noticed any difference in anxiety or stress during the day. I might start supplementing at night.

This product works...almost immediately but there is a catch! I felt woozy and tired for the whole day. It actually made me sleepy and "heavy-headed". I couldn't concentrate at work but took it for 2 more days in order to find out the culprit. Needless to say that was a bad decision! I was fatigue the entire week and it actually took me a while to recover. I hated the feeling after taking suntheanine, it felt like someone was controlling my brain. Advice: Take this only when you are very very very very anxious.
