If I missed this point somewhere please excuse. Ranger, most people don't understand how pain meds work and if you take one in fornt of somebody you get that look. After you've been on one type (class) of pain meds your body habituates (Gets used to it ). You can take more of the same drug for the pain but the body uses only the amount that it neededs for the pain. If you got a decent doc he/she should be able to switch you to something (different class) that will work as well. Been on that rollercoaster for years. Never get good sleep because of the pain.
