Just in case no one else knows, watermelon lowers your blood pressure. In my case my blood pressure got to 103 and I felt bad. Very dizzy. I was eating a lot of it for a week as it was so hot out and cold, sweet watermelon was so refreshing. Ack!! Beware the delicious watermelon (or don't be a pig and eat a whole one by yourself).
May all your blood draws be painless.
