Hi, my problem with sleep is somewhat different. I either sleep, or I don’t. When I sleep, I can’t wake up. Or, I can’t sleep at all during the night. All or nothing, very strange. Then, like a few had said, we get used to it. Unsure if ‘the biscuit’ is the answer, I shall wait for more results. I don’t get up on my ‘no sleep’ nights. I self relax my body, so at least I’m resting, but it doesn’t take me to sleep. Nights that I do sleep, my husband wakes me , that way I keep to my sleep pattern. If my husband is not home, I sleep until someone wakes me. Could sleep around the clock. During sleep, I shout out, wave my arms around, fight, have night terrors, but I’m still sleeping. My husband just tries to calm me until it passes. During the night terror I’m obviously frightened, as my reaction shows, but I don’t wake. The following morning I remember the horror of it. All very strange, but then, that’s Parkinson’s for you.
