Poor sleep quality and length after THP

Is it normal to be woken through the night following Total HP? Had mine 21/2 wks ago and although mobility good during day I am unable to get more than 3 hrs sleep before being woken by pain and cramps. Think lack of sleep is hindering my recovery and none of the medications suggested have subdued the pain and cramps. Soooooo exhausted and desperate to get a good night's sleep! Lou
