daisybun,
About two years ago I had all sorts of tests done in an hospital and my blood sugar was one of the things tested and nothing bad was found.
My heart was beating fast but it stopped like one minute later and it was back to normal.
About twenty minutes ago I took some aspirins, until then I was again close to either an headache or migraine or having my head spin and it looks like it's gone now.
I often freak out when it has to do with my health so it's weird that what happened this morning did not freaked me out, it did not even worry me which that too is weird.
