I am on 160 MGS. of Methadone and have been clean of opiods for 2 years now. I have migraines, disc fusion in my neck, and fibromyalgia and occassionally will need something for the migraines. I went to an Urgent Care Clinic the other day and had been vomiting for 3 days with a migraine. They didn't ask me about methadone specifically, just the drugs I was on currently and I did not tell them about the methadone. BIG MISTAKE! They gave me a shot of Nubain and Phenergan and within a minute or so I was thrashing about vomiting worse and having diarea. I got the nurse and told her in between vomiting what was happening and they made me sign out and go to another hospital. I thought about going home instead but I thought I would die so I got my son to take me. I felt like there was hot lava running through my veins, my heart was going to burst, and I was spastically moving like Parkinsons disease. I had no control over my body. I kept uncontrollably yelling out also. The ER made me wait awhile before seeing me also and didn't act like it was an emergency. When I did finally see the doctor, he gave me something to calm me down and lower my blood pressure. I will never forget to tell anyone about methadone again! Somehow doctors and nurses need to know the consequenses to help us idiots. I had no bad intentions to get high. I was just sick with a migraine and didn't want the prejudices of the nurses and doctors knowing I was on methadone. I didn't think it was imporant. Doctors don't tell us the importance of not mixing the drugs.
