I'm having my tooth extracted on Friday under anesthesia and will be put on narcotics for a few days after. I'm so scared because they cause so much pain and constipation. Any suggestions what I can do during this time to lesson the constipation. I'm really desperate!!Under normal circumstances I live on a bottle of Mag Citrate everyday, but with the narcotics its not going to work as well. Has anyone got any suggestions or been through this?
