Has anyone tried Losartan for Autonomic Dysfunction problems, specifically early am wake up with huge adrenal spike: 30 point increase in HR, sweating, hot flashes, anxiety, blood pressure drop, BowelMovement, weakness, shivering, nausea and/or dry heaves. Then takes 2-3 hours to return to baseline feeling of sickness. Only med I have taken that has provided any relief is Klonopin, but am becoming acclimated to drug and do not want to raise dosage. Considering Losartan trial based on recent studies where drug was helpful to several patients with Autonomic Dysfunction issues. Mostly drugs give a negative reaction. Thanks.
