I moved to Britain from the United States a bit over a year ago and have been using OTC codeine products to treat my pain for a long time now (it's legal here), to my own detriment. I've lost my appetite completely and can tell my stomach lining is suffering - the nausea gets pretty bad during the day after I take it, even if I drink a full glass of milk or have a full meal. Please don't make the same mistake I have if you ever find yourself in the UK or another place where OTC codeine products are legal. Seek help from a doctor for your chronic pain, if you have it. I threw out the last of my Nurofen Plus a few days ago and my daily pain is worse than it has ever been. Big warm internet hugs for anyone else who might be going through something similar. You can beat this dependency; you are not alone.
