oh boy

The night before the heart cath and for some reason I can't sleep.  Something just seems a little off and I can't quite put my finger on it.  I went to my PCP today and he is prescribing some low dosage of diabetes medication for me to try after the procedure because the dye for the cath throws all the readings off.  I'm taking this God-awful tasting stuff to help the dye get out of my body so it doesn't damage my kidneys.  I don't know...something just seems off tonight.  Guess we'll find out after tomorrow! :)
