Please do not start any medication without a proper diagnosis. Morning dizziness lasting for a month can stem from various causes, such as dehydration, low blood pressure, blood sugar drops, or inner ear issues like vertigo. To pinpoint the cause, it would help to know: do you experience a spinning sensation, nausea, or ringing in your ears? Are you taking other medications? I highly recommend consulting a healthcare provider for an evaluation. For now, avoid jumping out of bed quickly; instead, sit on the edge of the bed for a minute before standing, and ensure you are drinking enough water.
