Hi was wondering if taking 2-2.5 20mg doses of propranalol, before bed, could cause my blood pressure to fluxuate enough where I get severe "Chills!!??" This happens as soon as I start falling asleep;( soooo frustrated!! My dosage was recently increased from a single 20mg dose, because I was having occasional night palpitations, when lying horizontally, in bed, or in a recliner. I look forward to your response;) Thank You
