Welcome to NeuroTalk, Pud's Friend, Nice to meet you.
My Doc kinda pushed Avonex at me, so I tried it for 7 mos. The side effects wouldn't let up, so I stopped it. A couple of years later My new Doc pushed Copaxone at me, so I tried that for 11 mos. It was not helping me...I progressed to SPMS while on it, so I stopped it too.
A few years later (April 2003) I discovered LDN (Low Dose Naltrexone) and am still on it. It wasn't on the approved NMSS list, so my Neuro wouldn't Prescribe it. I found a lovely Doc in Pennsylvania, who, kindly, prescribes LDN for me.
Good luck with your choice of DMD and I hope to see you around this great place..
