Hi Hala, Thanks for writing to us, Tramadol is a narcotic drug which is usually used to treat pain due to several causes. It contains opioids which has a potential for dependence or addiction. When an individual takes it for a long period regularly, the body undergoes certain changes leading to problems when the drug is abruptly stopped. In your fiancé s case it is likely presenting as irritability and low mood which is why he appears to become boring and mean. The solution to this is detoxification which can help him become his normal self even without taking tramadol. This can be done by a qualified psychiatrist. It is suggested you take him to a Psychiatrist at the earliest. Hope this answered your query. Dr Anjana Rao Kavoor
