Hi Lucy,
You have been on propranolol successfully without that side effect, and I highly doubt you would suddenly have that particular side effect at a higher dose. I tried propranolol a few months ago and had trouble breathing on the starter dose. Once I figured out it was the propranolol, I stopped taking it.
If for some reason you do have a reaction -- and I know this is one of your biggest fears -- it won't completely restrict your breathing, it's just a little uncomfortable for awhile... like you're wearing a turtleneck that's a little too tight. The good news is that the medication will wear off in a few hours and you never have to take it again at that dosage.
Maybe you could break the 40 in half and take 20 to see what happens, and then take the other half if you feel okay after 30 minutes or so.
