Prior to diagnosis, I had very mild cataplexy. I didn't even know it was unusual to feel weakness in your limbs when you laughed. However, it has progressed over the last couple of years to the point where I started falling down this year. It doesn't happen often, but when it does, it hurts. As much as I hated the thought of trying Xyrem, I finally decided to give it a shot just because of the cataplexy. Turns out, it wasn't scary at all. The cataplexy AND the EDS are so much better after being on it for two months. Oh, and it's kind of nice to be able to sleep longer than an hour at a time.
