hi sir/madam, welcome to health care magic, I can certainly understand your concern about your drowsiness because of cyclobenzapine, as it is a muscle relaxant , so could be due to that you are experiencing drowsiness and tiredness. I can suggest you medication ie prothiaden, which can give you relief from your chronic pain with little sedation, that does not bother you. I have observed good results in many pateints with this complaint, hope you recover soon post your further questions if any, I will always be available to answer them Thank you.
