Well it started out pretty much exactly as you describe . However , I then went into full blown DKA diabetic ketoacidosis , which includes fun things like vomiting , extreme thirst , dehydration , hallucinations , extremely painful and labored breathing , severe hypertension , tachycardia , loss of consciousness , vomiting and urinating all over myself in bed , and 4 days in the hospital ! Bonus ambulance ride included , though unfortunately I wasn ' t conscious at the time so I don ' t remember . Not trying to scare you , just letting you know it can be serious , which is why the nurse made it sound urgent . If you really want to test your blood sugar before going to the doctor , you can get a cheap glucometer at walmart . But definitely still see a doctor .
