My soon to be ex husband is addicted to prescription painkillers, the doctor prescribed a different drug whilst telling him not to use the current one, it lasted a week until he was back on them as he could not cope without it. His mood can change with the wind, l have seen him get shaky and anxious when he needs his tablets but he says its the pain. He wakes very early then sleeps all afternoon. In the past year his memory has gone very downhill, he cannot remember something he has been told but also he has started to use words for clothing that he has never used before, ie singlet instead of t shirt, he refuses to see any problem but l can and l do not know how l can help him to see it.
