I was on Copaxone 20 mg daily for about 4-5 years. I didn't really improve, but didn't seem to get worse either. Then I went to 40 mg 3x weekly. I had worse injection site reactions, which I didn't like, and was frustrated that I wasn't getting better, so I stopped altogether. I'm thinking of going back to taking Copaxone, but I have moved to a state with poor access to appropriate medical care.
