I have been unable to sleep since my surgery. I am now 32 days post surgery, my surgeon and primary care both say that they have never heard of it. I did research and others have said the same thing, they are new insomniacs. I have tried lunesta,xanax,ambien,ambien cr, and temazapam,melatonin, and sleepy time tea. Nothing is working. Has anyone else had this problem? Have you tried anything that I haven't that works? My doctor says seroquel adds weight, have you tried it? Did it add weight to you? Any suggestions?
