Hi There After going through your query I understand your concern. I would like to tell you that Excessive Caffine consumption can lead to dizziness, palpitations, lightheadedness like symptoms and some serious health issues like trouble breathing, chest pain , hallucinations , uncontrolled muscle movements etc. kindly drink lots of water, mild exercise, and eat foods high in potassium or magnesium, such as bananas or dark leafy greens. Get an ECG and echocardiography done for essential heart check up and consult a physician if symptoms persist. Hope to have been helpful. Kind Regards Dr. Navneet Bansal
