i never had trouble sleeping but since I've had a new hip replacement recently I just don't sleep. The urge to move my legs is constant. Then comes the urge to keep moving my entire body. I sit up, walk, lie back down, get up, move iponto a recliner chair, legs start that horrid crawly twitching sensatiion so get off recliner, make a cup of tea, go back into the cold bedroom This goes on all night. Doc given me zopliclone and diazepam but it doesn't work.
