It is important to continue your medications for now, as stopping them suddenly can cause dangerous spikes in blood pressure and blood sugar. Your symptoms, like tiredness and sleepiness, could be due to low blood sugar from Gluconorm-G1, or side effects like headache from Telista 40mg and Amlong 2.5mg. Please monitor your blood sugar levels when feeling tired. Do not panic; these side effects are common and manageable. Contact your doctor promptly. They can safely adjust your doses or suggest alternative medications, such as different classes of blood pressure or diabetes drugs, that may suit you better.
