I am having alot issues with keeping my blood sugar levels up. well when I take my meds at least. I am having huge drops down into the low 60's. today it dropped down to 98 which is ok but I could feel it really dropping so I ate me a tuna sandwich which should have brought it up with the white bread and mayo but instead it dropped on down to 81. it is up to 107 right now but my heart is still pounding! feel all shakey too. anyone know what this could be? any experience like this? my chest isn't hurting but feels sort of strange. shakey strange
