Caused headaches
Although this product served as a sedative sleep aid, it unfortunately caused headaches, lethargy, depression, palpitations, and a general unsettled feeling. After a few days of use, I realised it was not suitable for me and I won’t be continuing with it.

RLS pain relief
I initially took 150 mg of Suntheanine during the day, but it made me dizzy and drowsy, so I switched to night-time use. While it helped with RLS pain, after two weeks, I experienced severe irritability and a raging frontal headache. I stopped using it, and my adverse effects improved within two days. I aim to use it only for severe RLS episodes going forward.
