I am 3 weeks post-op from a Hemorrhoidectomy and was prescribed Lortab 7.5. I only used it for the first week. It takes away the pain within 30 minutes, but I cannot sleep when using it. I was also prescribed Valium for sleep, but hesitate to take both. My bowels are working fine, but this evening I did have some bleeding and a lot of pain with just plain urination. I took 1 Lortab 7.5 at 11:55 and am still awake at 7:16 am. Pain is gone, but why can't I sleep?
