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'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'll feel some of the effects for that long, which is really nice when you have a stressful few days."
