General nervouness and weakness could be caused by organic diseases such as anaemia, chronic infection or thyroid disease, and a general physician would be able to determine if such causes exist. In general, such common symptoms are best managed by reducing stress and by ensuring appropriatte exercise, nutrition and rest. Drugs should be avoided, although herbs such as ginseng, ashwagandha and guarana are helpful. Vitamin complexes could also help. Valerian at night can improve sleep. Yoga, meditation and group exercises with social interaction are always beneficial. In some cases, psychiatric assessment for disorders such as depression will be needed so as to enable prescription drugs to be given under supervision.
