I have been going to a pain clinic for several years with back problems caused from a car accident. I started out taking hydrocodone 5mg. 3 x daily then went to methadone because the hydrocodone was not working. At the time I worked in a hospital and could not seem to function on the methadone, I was not able to stay awake. The clinic then changed me to 7.5 hydrocodone 3 x daily. Again after a while they didnot help. I was then changed to 10mg. first 3 x daily then 4 x daily. I have been on this dosage for about 4 yrs. I find that it is not helping very well and sometimes need to take more. It seems like that is all I do is take pain killers without a lot of relief. I was told by a friend of mine that Percocet 30mg. is alot better pain reliver. Is this true? Is it a extended relief tablet? What would be the dosage for this switching from 4 hydrocodone 10mg. daily?
