I took the one hour glucose test Monday. They said they didn't like how the test came out so they want me to do the 3 hour test. I'm not feeling good about it. The one hour test wiped me out the rest of the day and I had a headache the following day. Since I already have blood sugar issues I basically follow a diabetic diet anyway I can't see how this test would really be a good thing for me. I could use some advice on this.
