Strange: It sounds like your doctor has ruled out most immediately dangerous disorders. If malnutrition is truly causing this it might be worth searching for which vitamin is deficient. Most importantly, why are you malnourished? You should look for medical and psychiatric explanations if you don't know already. You are also on several medications which might have these side effects.
