Hello. I am a 25yr old woman (smoker, thin, only slightly active and I have no family history of serious issues except cancer) who has recently gone to the doctor for the following problems:

frequent urination
excessive thirst
abdonimal pain (intermittent)
extreme fatique (mostly around menstration)
headache
pains in legs, arms, back, neck, face
restless sleep (awaken to urinate or just randomly)
switch between constipation and diaherrha

My doctor tested me for diabetes, Lupus, Sjogrens, and thyroid disease and the tests did not show any of these. However my tests did show I have depressed (low) HDL and low white blood cell count. So, my doctor is suggesting I get more sleep, exercise and take Detrol (a pill to stop the frequent urination.) I know the things he listed for me to do could be helpful, but I feel there is an more serious underlying issue (besides bad sleep habits and OAB/overactive bladder) that are being overlooked and need to be addressed.

Is there anyone who can offer advice?
