first post, hello

i've been prescribed with propranolol, 40mg twice daily......my sleep is a bit messed up at the moment so took my first one when i woke up at 11.......i know i will be up until 3 or later tonight so trying to space them out so i wont be feeling too bad when im trying to get to sleep

i'm trying to wait until about 8 for my next one but feeling a little bit edgy now.....

anyway, the original question.......how long does it take your body to metabolise (sp)?...could the 40mg all be used up by now and that's why i'm back on edge?

cheers
