Does anyone have any experience of taking Low Dose Naltrexone? I've now sourced a compounding pharmacist and doctor who will write a prescription in UK and am all set to try it. As I understand it, you take it at night, it dampens down your natural opiads for a few hours after which the body reacts by increasing endorphins and opioid growth factors, these in turn cause the immune system to strengthen. As such it's a very different approach to treatment. It's apparently very safe because you are taking such a tiny dose. And it's not expensive.
