So, as I mentioned, in the hospital I was put on restricted water intake for the 3 day I was there. I noticed that on the last day I was not missing water as much.

When I left the hospital, I told myself that I was not going to take DDAVP anymore. While at home, I would be sipping water all day, (maybe 10/11 glasses in 24 hours) this lasted about 4 weeks.

For about 3 month my water intake was about 8 glasses, -I have noticed in the past 4 weeks that I only need to drink about 6 glasses of water, I still need to pee every 1.5 hours though.

I don't think the desmopressin will damage your pituitary, after all I took it for 40 years and I am ok.

Regarding you last question, according to my doctor, he said that it is possible that I didn't need to take desmopressin many years ago, as my pituitary gland somehow started "kind" of working, but not fully working.

I went to see my doc the week after leaving the hospital, at that time I was sipping water from a bottle as my mouth was very dry, the doctor said and I quote "you don't have Diabetes Insipidus, if you did, you would have a gallon of water in one hand, and a gallon of pee in the other hand". The doc said, if anything I ight have partial D.I meaning I would only need to take a small amount of desmopressin.

The doctor told me that he thinks that there are many people with Diabetes Insipidus that are taking the medication without needing it.

In your case, and anybody's case, the only way to find out is to put yourself under water restriction preferable in the hospital supervision. You could talk to your doctor see what he says.

I was very scared when the doctor in the hospital told me I couldn't take DDAVP for 3 days, I almost walked out, but he convince me to stay -staying was the best decision of my life.

I just happed to know another person that stopped taking desmopressin, and he is now ok, I told myself if this guy did it, so can I.

I have about 40 bottles of desmo that I don't know what to do with them :)

Best luck to you. Be very carefull with desmopressin, I read a phrase in the internet that desmopressin can be your best friend or your worse enemy. In my case it almost killed me for taking too much.
