G - ALS is not the only disease that causes this problem, so please don't relate your being unable to sleep as a sign of ALS. I, too, went through that stage, and still do sometimes, where I could only sleep in one hour intervals. Between the vibrating, twitching, nervous feeling in legs and chest and somewhat of a "speedy" feeling, I could not sleep. I know many pals use amitriptylline for sleep. It is not a serotonin drug, so maybe it will help for you. It does cause dry mouth, though, and pals also use it for that. Many others on her use sleep aids. I know Annmarie and Jamie take Ambien. If you try something short term, maybe this will go away.
