A friend had a heart attack, had an operation before, and suffered from chronic insomnia.

If the patient's insomnia is caused by postoperative pain, it is recommended that the patient take oral analgesic drugs to relieve it, such as ibuprofen; if it is caused by excessive tension, oral nutritional nerve and sedative hypnotic drugs can be taken to relieve it, such as mecobalamin and dexzopiclone.
