I'd start with the 24 Hour Body Clock and compare what it indicates with the hours you are awake.

The theory is that if you are waking up during the times indicated, you have something going on with that organ.

Example:

Compare time-frames and side effects of medication you take - or exposures that exit through that organ - and see if anything lines up.

In my experience, it often lines up during my waking hours. YMMV
