halfin ... my hunch is that benign twitching can be much stronger and more annoying than that connected to other, more serious, neuro conditions. With frequent, strong twitching, it is a constant reminder that Something Is Happening, so if people are already nervous about their bodies or have some underlying anxiety, it keeps them on edge. It's like earthquake aftershocks: you react much more strongly to the continuing small jolts than you did to the first big one.
Although I have ALS, I have found that some symptoms (euphoria, intensity of connection to the natural and spiritual world, some physical experiences, such as intensified physical pleasure [oh, do showers feel good! and so do waves of goosebumps) feel great. Other symptoms, not so much. :lol:
As the politically incorrect like to say: Might as well relax and enjoy it.
