I started on it in May. I don't see a difference, but my bf says my gait is better.
I've heard anecdotaly that it can take 9 months to see results; I've also heard that it helps in only 40% of patients.

I tried it, twice. I couldn't handle the side affects it gave me. Try doing a search on "Ampyra" to see all the past threads on the subject for more information than what folks post here.

I have been taking this since it was approved, February or March I think it was.

When I take it, my walking range and balance definitely improve. When I don't take it, I definitely see a difference.

Waking up in the middle of the night for *one hour* was being a problem, but I changed the schedule just a bit and this isn't as much of a pain.

I tried it when it 1st came out. HATED IT! LOL
