Suggest Medication For Poor Appetite, Depression And Fatigue

Hello Dr. Samuel. N. Grief, My husband has myelodysplasia ,since Oct.2011. He receives Blood Transfusions every 3 weeks. When he first started receiving Blood Transfusions his blood count was in the 70 s, then went up to 80 s,90 s& got to 100. Never stayed at any level too long. Now this past week his count was 97 in Feb.19/2014, & dropped down to 82. on March 11/2014. About 6yrs.ago he had an abdominal aneurysm (almost lost him). In the yr.2011 he had hernia operation &yr. 2013 he had gall bladder operation.After all this, I would like your opinion on what to do to make him feel better& get his blood up to a higher level.He has a very poor appetite & seems to fall asleep at all times. He tires out very quickly & has no interest in life itself. Is there any Meds. available for something like this to make him feel better. Please Help. Thank-you
