Ultracet and Ultram are a man-made (synthetic) form of an oppiate. They can be addicting and withdrawals from these pills are just as bad as withdrawals from opiates.
So please, please be careful! I know you are having legitimate pain, but just don't fall into the "trap" that they are non- narcotic and non- addicting because they are! And, again, NO FUN to come off of!
There is a website (somewhere by some gov't group) lobbying to make this drug a controlled substance because of the reported abuse and addiction already. Interesting, huh? I am sure they are some here who could chime in with their own Ultracet/Ultram horror stories....
Not trying to scare, just want you to be aware and use them wisely for your pain. Take care and God bless,
