Hi @Whatnext2018 I have many of those symptoms and have done for some time now.
I often have exactly the same feelings dropping off. Like you, it's a feeling like it could be anxiety but there's no reason behind it, just totally random. I always wake up in a bit of a state too - feeling of panic and dread.
Over the last couple of weeks I've started getting more and more similar symptoms in the day. I'm very jittery and my teeth chatter a lot. I also get a funny feeling in my jaw as if my muscles don't work and I frequently have headaches. I don't get tingles (yet!) though.
I've reported all these symptoms to my GP. To be fair, she's pretty thorough (I've had lots of other tests over the last few months) and she's not seemed particularly concerned so I'm trying not to worry about them. Like others have said, I'm wondering if there's a link with the vagus nerve/ our parasympathetic system.
I still sleep really badly but find lying on my tummy listening to a lightweight podcast helps. I also take CBD oil but not sure how much this is helping. I've just started taking a magnesium supplement before bed too but it's early days yet.
GP wants me to take anxiety meds but I'm resisting at the moment. I feel too scared to be sedated as I worry about my heart rate and breathing at night. I'm starting talking therapy on Tuesday but don't have great hopes as I think frankly it will exhaust me.
I'm on day 86, so coming up to 3 months now 🥺.
