"i have a lot of pain issues. mainly replaced c4 c5 disc then fused and c6 c7 disc replaced then fused and fibro. i have a high tolerance for medication, my body adjusts very quickly and suddenly i am on the highest dose and then it doesn&#039;t work. last month i weaned myself off of 160mg of methadone a day in like 3 weeks. anyway, nucynta is new, it is my last hope. i am very scared about this because i am already on 100mg 3 times a day and sometimes i take an extra just to get through the day. i can&#039;t afford this but i don&#039;t know what else to do. it does cause nausea and dizziness a little disoriented but those symptoms are fading.
