I've actually been thinking about this quite a bit. The SPS meds gave me about three months of normalcy before my body adjusted and they stopped working. I had adjusted to this slow decline, and was hoping they'd find something that would slowly reverse it and I'd regain everything I lost over time. Instead I had a night and day difference and was able to do everything I used to do and started planning out a career and vacations, etc. I was able to get out to a baseball game and thought I'd get back into photography. I'm still hopeful things will get under control, but its definitely harder to regain something and then lose it again then it was to go through it the first time.
