I desperately need beta blockers for anxiety and migraines but even though the pharmacist and neurologist says a minimal dose will be fine 10mg bd, the GP says it's too dangerous for my mild asthma. So now I've convinced myself that taking the pill will make me struggle to breathe. Mind over matter, yes, but I've convinced myself of the side effects before even taking it. Has anyone else on here had propranolol and asthmatic?
