Hi. I started Zelnorm about three weeks ago and it has helped with my pain and nausea tremendously. The only thing I notice now is that I am so much more tired than I ever used to be and I haven't changed anything else. I am wondering does anyone else have this side effect or is it even a side effect? I mean I can hardly pull myself out of bed anymore and feel like I need toothpicks to keep the eyes open. It just seems there is always something new popping up!?!?!?
