Hello. I'm extremely worried again. I believe I have a very high tolerance to narcotic pain meds. Everything was really fine till recently. I was on 10mg Oxycontin and then told my doctor that stopped working and then my doctor increased it to 20mg...then soon later, say a week later, told my doctor it's not working. I'm losing my mind completelly.

My doctor is nerveous on me. Since I have lot's of 20mg oxycontin left he said take them together and come back again for the 40mg Oxycontin.
When will this end??? I feel like a complete failure.

My doctor told me he has a patient who has been taking 20mg Oxycontin for years now with no need to increase. What's wrong with me??? Is it a weight issue, let's say if I put on weight will this stop this high tolerance to narcotic pain meds?. I'm 5'4, 107-108 pounds.

Should I go back to Percocet, perhaps it's less addictive?. but percocet only helps for 3 hours. I'm not sure what should I do now. Is it cause it's chronic neck pain + TMJ that makes me with such a high tolerance to narcotic pain meds?.

Is it better for me to go on a patch?. but then the patch will stop working. What's WRONG with me?.

Please anyone with answer help me. Thanks in advance.
