Thank you. My husband is constantly tired, sleeping the majority of the day. He is losing weight and feels weak, (20 pounds lost in 6 months), yet eats normal. He had Leukemia 7 years ago so his Oncologist checks his bloodwork, it s fine. He has daily constipation problems too. His doctor can t figure this out, but SOMETHING is wrong and it has me very worried. Thank you, but I didn t realize there was a charge. Thank you for your time, but never mind.
