I agree that you may be over medicated on aspirin,
and especially if you are having
nose bleeds. The danger is internal bleeding (abdomen, bowels, brain, etc) and there may not be any warning until an emergency condition and that could be fatal.
I take a 80mg aspirin, and had a wisdom tooth pulled. It took awhile to control the bleeding, but told to bite down on a tea bag to help stop the bleeding. For an internal surgery, it is recommended to be off antiplatelets for 7 days.
