Since you are already on multiple long‑term medications for hypothyroidism, diabetes, and blood pressure, it is important not to add or continue supplements without medical supervision. The restlessness and disturbed sleep you noticed after starting Stress Shield suggest it may not be suitable for you. The safest step is to stop the supplement and consult your doctor, who can review your medical conditions, current medications, and overall health to determine the most appropriate treatment. Managing stress and sleep often requires a combination of correct medication, dietary adjustments, and lifestyle measures, but these should be tailored to your individual health profile by a qualified clinician.
