Hi welcome to HCMForum. The thirst you had is not due to dehydration
but due to anti histaminic action and vasoconstriction
. and also due to frequent urination
of some reason.
Frequent urination may be due to urine infection diabitis anxiety
etc. i advise you to consult a physician for diagnosis and treatment. you may have to go for blood work to exclude diabitis. you have to get treated for diabetis or infection if they are there.
Iadvise to follow some divertion procedures as yoga meditation
reading hearing music if interested gardening if not interested in any of these engased in some thing which you like more. try not to think of your problem any more. thanks forr calling.
