I am a 37 year old female on Methadone Maintence for about 4 1/2 years. I have been having issues lately with my dose being stable. The doctor at my program suggested I have my thyroid tested for underactivity due to symptoms such as weight gain, eyebrow loss, sluggishness, numbness in my hands, swollen feet, legs and hands plus family history. There is also a family history of early menopause and my hormone levels show I am in that range.
