Any side effect yet? I took L theanine and thiamin for 1 month... it did reduce my anxiety little but, but i started getting nauseated and started having stomach problem. The symptoms went away 1 week after stopping taking them. Also, differnt time, i took Ashwagandha, and i started feeling very dull after 1 week. Basically i woukd get very sleepy, and had brain fog all day long. Maybe this is very specific to me. Most medications don't agree with me. So nowadays do breathwork/journaling/medications, which has calming effect before meetings.
