I was on a medication to manage nerve pain, which was Lyrica based and I have since found that the doctors were just treating the symptom and not looking for the cause. The medication caused a few issues including health issues due to my diabetes which it threw out of whack.
Unfortunately, the medication also caused other mental health problems which I was unaware of until it was too late. I have since gone through the detoxification process and am no longer on the medication. A friend has since told me that the side effects will most likely last for longer than I was on the drug. Bit scary when I think I was on it for 18 months, so I guess I can look at potentially 2 years of insomnia.
