My Husband Has Been On 100 Mg Zoloft Once A

My husband has been on 100 mg Zoloft once a day and 25mg of Clonazepam twice a day for three weeks. For the past 2 days the doctor advised to add one more Clonazepam a day.His depression has deepened and is so tired but doesn't get a good sleep. His anxiety is down but does not want company (even family) and has no energy to do anything. Do you have any suggestions what he could try?
