Anxiety
"I take 0.25mg whenever I feel anxious with some propranolol to calm down my heart rate (sometimes feeling my heart beat fast can cause anxiety), and it usually does the trick. I&#039;m switching to 0.5mg in hopes that I can just take one 0.5mg pill without the propranolol. Just so you know, the half-life of this medication is 18-50 hours, meaning you&#039;ll feel some of the effects for that long, which is really nice when you have a stressful few days."
