hi, an in-law has lost 36 lbs., suffers from nausea, loss of appetite which in turn have resulted in dramatic weight loss, fatigue, hand tremors, loss of strength (can t stand up for more than a few minutes), difficulty focusing. He currently a patient at UVA Hospital in Charlottesville, VA. They can t find out what s wrong, and are reluctant to try. Any experience with anything like this? Thanks.
