Dear Sir/mam,   I had been consuming 300-400ml Codeine phosphate & CPM with atleast 1mg of Xanax daily for past 5 years. i am sober now for 3 Days without any problem or complications.   I want to know which tests should i undergo to assess the the physical damage to my body.   Which organs are most affected, and which complications are waiting ahead such as liver, kidney, allergies (by antihistamines) etc. ? Plzz Reply Asap. I am doing my best to prevent relapse. I hope it will help a lot of people since rarely an addict comes forward to ask for help. Yours Sincerely, The Anonymous.
