The Water Deprivation Test

Right now my excessive thirst is making me nuts. This thirst, drink, urinate cycle is causing more trouble than anything. I can't get any sleep and am tired all the time. I thought that the fatigue was the WG, but now that the prednisone has helped all my other symptoms I think the fatigue is from my disrupted sleep patterns. I go to bed around 1am and wake up every 60-90 minutes to drink and pee until about 4:30am when I pump (which I will stop doing shortly). I then go back to sleep from about 5:30am-8:30am, waking up once or twice in that stretch. It is really driving me crazy. Dr. Awadh thinks I may have something called diabetes insipidus (unrelated to the more common diabetes mellitus).

Today was really rough. I had to take a water deprivation test to test for the diabetes insipidus today. I wasn't allowed to drink any water after 3am until my blood was drawn at 9am. This was pure torture since I have a huge thirst problem. I drank a ton of water at 3am, but woke up at 5am and couldn't go back to sleep because I was so thirsty. I kept getting up every 10 minutes to swish water around my mouth and spit it out.

After the test, I saw Dr. Awadh to discuss the results of both it and my lung biopsy. Dr. Awadh said the labs did show I had diabetes insipidus and he has referred me to a nephrologist. He said that the lung biopsy showed necrosis, but no active vascultis. It was negative for infection so he wants to start me on the Cytoxin.

I am planning to start taking the Cytoxin on Thursday morning, which gives me a couple of days to wean Amelia over to a bottle. Sob. :(
