Yes, it's definitely not "anxiety,'' Similar to you, I had no troubles falling asleep. When I first started feeling the bed shake at bedtime while watching a calming TV show, I was still able to fall asleep after the occurrences. Then, they increased in frequency and duration over a few months becoming so severe I couldn't fall asleep or would be woken up. I've had some other weird novel symptoms and events happen like Benign Paroxysmal Postural Vertigo happen during sleep (being woken up by the vestibular event), and the internal shaking progressed quickly after that but it also wasn't the cause. I also have an autoimmune disease (UC/IBD)....but all of this is New. It's good to hear you were able to get it under control after several months, thank you for the encouragement and sharing of advice. Good to know.
