Sadly, I have been a vicodin abuser for almost a year. I will go weeks without them, then come back to them. After reading forums such as this and researching "Withdrawal Symptoms", I can admit to having a few of these. However, am grateful that at least for right now, they are not severe enough to where I am unable to function without the pills. Like everyone on here, I want to be done with them completely. My work, social life, etc, do not suffer for the moment. (My concentration with school has actually increased significantly and have gotten nothing but 4.0s in Graduate School). I do know it is time to quit and just be done. I am able to function without them as I stated. My question that has been difficult to find an answer to, relates to long term effects. I have not been able to find at least an approximate length of time or dosages that can lead to eventual liver cancer in the future. I am currently 26 years old, in relatively good shape physically, do not drink or have any other vices that may exacerbate the vicodin effects on my liver, but am still concerned. I do not know if after a year of off an on usage will inevitably lead to death by liver cancer by the age of 30. I am aware that this is wrong, and with the help of forums like these, am working harder than ever to stop usage completely. Any help would be most appreciated. Good luck to everyone on here, that may be going through a similar situation as I am, or worse.
