you'd think i'd be a pro by now

Today was my 5th glucose test in 2 years. I'm insulin resistant so now that I have been back on my full dose of meds, they have have to make sure everything is working. I've done this so many times, I know what flavor drink I like "best", I know to bring something to read for two hours of waiting, I know what to eat the night before so I'm not starving by 10:00am, so you would think what happened today, would not have happened! For those of you who have never experienced a glucose test, they draw a vile of blood, make you drink this really sugary, syrupy drink, 30 minutes later they draw more blood, 30 minutes after that they do it again and then one hour later they draw another. Then you are done. Well today, I missed the first 30 minute interval, which means I could have wasted all that time and choked down that drink for nothing. I was thinking I needed to wait an hour, then 30, then 30 more but I got it backwards and failed to pay attention to the times on my time card. Sooooo they let me complete the test and if my results come back abnormal, I will have to go back. I don't know what I was thinking but I was so mad when I realized I had messed up. It literally threw me off for the rest of the day. Crazy girl!
