I think that's a good guess. I've had to piece this info together for myself... I supplemented my adrenals and it caused me to stop wasting sodium and start wasting potassium... along with urinary frequency it caused muscle spasms. are you having muscle spasms? I think it's because my entire HPA axis is under functioning. If you are having muscle spasms as well, try supplementing with potassium and see if the urinary frequency subsides. As far as i can figure, anti diuretic hormone helps you to hold onto potassium. Also consider pituitary/hypothalamus glandulars. I get mine from a company called Biotics.
