I have Thal B Minor from my mother's side. My Hemoglobin is 111 g/Lt. I was diagnosed with Hoshimoto's early this year (Jan-2011) and take 5mcg Thyroxin. My recent 2 blood tests show slightly low platelets 112 and 116 . My W & R BC are normal range. My RDW is 18.2% (above range. I feel tired and sleepy lately and have little endurance to walk > 1 km. I am 58 y.o. I have an enlarged prostate (98g) that constricts sometimes and I take Flowmax when needed. I have spells of ED. Over the past 10 years I noticed a material decline in my stamina, strength, alertness and sex drive. I am concerned that my health is also reducing my ability to work and therefore my economic well-being as well as my physical and emotional health. Any suggestions on mitigating my tiredness and lack of drive?
