It is normal to experience some anxiety and fatigue, especially during normal daily activities. Treatments can help you manage anxiety and carry on with your daily tasks. It is not unusual for anxiety levels to fluctuate, but the goal is to have more good days than bad. It may take 4 to 6 weeks to see how effective your treatments are. As for taking theanine with your medications, studies do not show concrete evidence of its effectiveness for anxiety. However, there are no known interactions with your current medications, so you could try it if you wish. If you are taking medication for high blood pressure, make sure to monitor it more frequently as theanine could potentially lower it.
