What pain meds do you suggest?

I fell 40ft. hit a stop sign on the way down shattered L2 and was paralyzed. Recovered somewhat but have regressed over the years. I also have burst disc C5-C6, T4-T5, fused L1,2,3,4,5, severe DDD and spinal stenosis and permanent nerve damage. I was taking 480mg Oxycontin daily, then switched to 200mg Opana daily. I am now prescribed 160mg Methdone daily. I will be seeing my doctor next week. I need to change from Methadone, I've been taking it for 4months, the Oxycontin and Opana I took for years. Methadone works well on nerve pain but I can't stay awake. I didn't have this happen with the Oxycontin and the Opana was okay. I have switched meds. trying to find something that works. The Oxycontin and Opana was up and down a lot while as I said the Methadone makes me so tired I don't do anything. I just lay around and hurt because I can't stand feeling so drained. I've been dealing with this since 1990. Any ideas?
