I was taking Vicodin 10mg/325 Norco's up to 10 a day and I built up a tollerance to them through my pain managment clinic. They wanted to put me on Morphine next for my TMJ, can't even eat without pain meds. I tried Muscle Relaxers everything! I finally weaned myself off of the Norco's because of the not only the tollerance but the stomach aches that came with that dose. I got a RX for Ultram aka Tramadol. Even though they say there is a risk of seizures with this medication, I haven't had any problems. It's not a contolled substance like Vicodin and but you do need an script for it in the U.S. so I buy it online and only take what was precribed to me. I was using www.usmedsrx.com  but found a better place and it's shipped to my door like clockwork www.medsrxshop.com less than 40$ for a 30 day supply and a lot less than the local drug store . I am not saying this is the best medication and always talk with Doc but it's a lot better than taking a Narcotic and has worked for me and I can take it when I need it and not as dependant like I was on Norco's . If you have TMJ or any othe cronic pain , I hope this helps.
