Nauseated on DDAVP Spray?

Does anyone else get nauseated when taking the spray? Sometimes I get sick to my stomach and
am very queasy. If I drink too much water while on DDAVP I get the dry heaves (when this
happens I just wish I could throw up!) I am wondering if it is caused by the spray going down the
back of throat and making me sick. I have limited my fluid intake and don’t get the dry heaves anymore.
