I used to take a high dose of co/dyd, and your right 10/500 is a very low dose, I found I needed high & higher doses of the codeine and used to take them separately, ie paracetamol + co. My doctor took me off of them and I now have Tramadol, they are good but you have to take a maintenance dose, and they are strictly control. At the moment I have a flair up of the fibromyalgia but am in constant pain, and its hard sometimes to keep a positive outlook. I wouldn't wish pain on anyone, but it is good to speak with people that understand! Thanks for listening. Lyzzie.
