Hello, Welcome, and thanks for sharing your concern I went through your query, and I feel, you should know that this medication is used for neural category of pain, and it has a side effect of being a sedative. Other side effects are Irritability, feeling numbness,increase appetite, constipation etc but sedation is most common. if you are having trouble taking medication, its not worth the trouble, stop it I hope my advice would have been useful, in decision making regarding your treatment, still if you have any clarifications or doubts feel free to contact back. Thanks.
