Someone said here that you are not failing the drugs, they are failing you. I tried Copaxone and suffered from fatigue so bad that I could not even get out of bed for days. Listen to what your body is telling you, not what others are trying to convince you! Stop the madness. It's ok to stop.
There are many people with MS who don't use any of the current DMT's on the market (me for one) and just treat the symptoms. Think about this, up until 1995, there weren't any of these drugs on the market for us. It was all about symptom management.
You have to do what's best for YOU. It's your body, your decision.
