Propranolol
"Using 40 mg every AM & 20-40 mg as needed for at five years, it’s my saving grace in most everyday situations that can cause panic or anxiety. I used benzos for 15+ years with a strong dependency, I honestly thought I’d never get off them, until Propranolol. One dose in the morning carries me through to lunch, and only if needed do I take more. The ER version lowered my pulse below 55, even at the lowest dose, and honestly it didn’t work half as well. Maybe it’s mind over matter but I start to feel relief from panic or anxiety within 15 minutes and I’m fine within a half hour at most. My advice to everyone-less is more, if you dose daily try a larger dose in the morning & half doses as needed, too much and you’ll be drowsy"
