You didn't mention how long you have been dx'd.
I personally was dx'd in June of '96 and I have been on all the ARC drugs, I started with Avonnex, then my doc switched me to Rebif, (claiming 'studies have shown, blah, blah, blah....'). I HATED the side efects of both of these drugs. The intense cold spells and once a week hangover with Avonnex, three times a week with Rebif.
I just ended up not taking the Rebif anymore because I was always feeling sick and week.
I switched to Copaxone. What a difference!
Copaxone has virtually NO side effects, (maybe a small bump at injection site).
I had to stop Copaxone for about a year and 1/2 while I particpated in a drug trial, (the ill fated MBP 8298/dirucotide trial). During that time span I went downhill quickly. It got to the point that I had to purchase a four wheeled walker to keep me upright.
I have restarted taking Copax and 1mg of Naltraxone as of October of this year. My strength is starting to come back, but I am still walking with a cane, (I was able to ditch the walker).
Incidently, Naltraxone doesn't work with Avonnex or Rebif.
My advice is, if you have insurance and can afford it, by all means
take the Copaxone!!
I had a slight limp before I stopped taking it, and thought that was the worst thing it the world. As it turns out I was doing very well and I had no idea how bad it could get without the drugs.
