Busa,
You're definitely doing the right thing. Lots of guys out there just accept it as the "normal aging process," and are miserable. Lots of uninformed doctors out there call it normal aging process too. Not the case with Drs. Crisler or Saya. They understand the importance of optimizing your hormone levels, so you can feel your best, and live your life to the fullest.
All of the symptoms you listed are classic low T symptoms. Another test you may want to look into is a Cortisol Saliva test. Saliva samples are taken at 4 different times in a day (Midnight, 8am, 4pm, 8pm). High cortisol levels at bedtime will adversely affect your sleep. They can also affect sex drive and mood. This too can be treated.
Good luck with your consult. Dr. Crisler will take good care of you.
