Also, for the love of science, don't go the "I'll listen to my body" route unless you are backing it up very carefully with monitoring to make sure that you're reading your body accurately. When people get sick or injured, or even just very stressed out, often their brain's interpretation of the signals they receive from their bodies goes all cattywompus, which is why it happens so often that a person "felt just fine" and kept doing the things that were killing them.
I can't tell you how many times I've had my ex almost bite my head off because I suggested his blood sugar might be low or high, because HE FELT JUST FINE DON'T TELL ME WHAT I NEED.
So just back up your impressions with your blood sugar monitor, to be certain.
