Dear hcm user. Welcome to hcm. I understand your concerns. You are correct. There are not many drugs available to replace lithium and almost all other drugs are for controlling and management of other anxiety and depression symptoms. I take liberty to suggest psychotherapy methods like relaxation therapy, cognitive behavior therapy etc. These time tested and efficient therapy methods will help you overcome the anxiety and restlessness associated with your bipolar. Over and above these help in management of up and down cycles. Believe me, therapy methods work wonders in bipolar disorder. Please consult a good psychologist online or in person. Please feel free to contact me for more information and guidance. Take care.
