Methadone Hydrochloride and testosterone

Hi,

I have hot flushes (feels like my body temp is out of control, with profuse sweating).
Morning aches and stiffness in joints).
I used to have sexual dysfunction before I started testosterone decanoate injection.)
I also used to have horrible fatigue and apathy.
I still have depression.
Since methadone has a negative effect on the various endocrinal mechanisms in the hypothalamus and pituitary, it makes sense that it would interfere with body temperature homeostasis.
I am on 100mg a day.
APC.

Been on Methadone tabs for 9 yrs. I gained 130 lbs, have edema in my ankles and feet for the past 8 yrs, I have an endocrine problem (pituitary gland doesn't produce testosterone anymore), I'm itchy all over, I get drowsy, and I have hot flashes. I think I should get off this drug and deal with my chronic pain. At least I'll lose wieght, stop itching, lose the edema and aching feet, maybe restore my endocrine system balance, etc....
Whata ya think?
