Your symptoms, loud snoring, daytime sleepiness, hypertension, tachycardia, and palpitations, strongly suggest a condition called Obstructive Sleep Apnea (OSA). During sleep, pauses in breathing trigger adrenaline surges that raise your blood pressure and heart rate. You should not start any medications without a proper medical evaluation. I highly recommend consulting a doctor or a sleep specialist for a sleep study. Treating the underlying sleep apnea, often with a CPAP machine or lifestyle changes, is the most effective way to resolve your daytime fatigue and cardiovascular symptoms. Please seek a professional medical evaluation promptly.
