Recently had a glucose tolerent test at gp. Came back that I wasn't diabetic . But having still bad symptoms and feeling quite ill. I have still done a blood pick test in a morning and when I feel really bad. I have headaches, dizziness, nausea, stomach pains, pains in legs, blurred vision and pain and pressure in my eyes, yeast spots, and had weals recently. I can cope with some of the symptoms together but I suffer real bad with tiredness to. My blood tests in a morning are 4.2 to 4.6 I eat breakfast but by time I start work a hour later I am feeling dizzy and sick with a bad headache.
