The only thing that I've noticed here within the past month that I've been on it is ALOT of nausea. After taking recommended dose, I am still in excruciating pain and cannot seem to go to sleep. Have to take Phenergan to help with nausea and then I'm off to sleep. Have to take it every 6 hours. I'm having to take it sparingly to avoid being nauseated all of the time.
