Oh I think you should do the test when you think it is best for you. That wasn't my point and I am sorry if you thought it was. My point was I didn't realise DRs surgeries had stopped FBG tests BECAUSE of DP. I knew they had in favour of HBA1C as I posted. Nothing to do with when individuals should test at all. I agree with you BTW - don't test if you cannot take any action. My DP kicks in when I get out of bed and hangs around for about 4 hours depending how active I am. Most often it seems people on this site test as soon as they can to waking up. There was even a thread of what that meant in terms of whether people got out of bed, washed hands etc so that shows how close some were to wake up and test. I also think the over whelming response to that thread was as long as it is at a consistent moment then that would be fine. Good luck with your testing.
