Quetiapine side effects - help! 🙏🏻

I was started on Quetiapine 50mg XL for insomnia on the 28th of January. It works wonders for insomnia, I'm able to sleep 8 hours and wake up rested. However 3 days after I started taking it I felt some physical anxiety like tightness in my chest and palpitations which are now gone, but I still feel slightly physically anxious, the anxiety being mostly felt in my upper chest, as if I had a not there and chills throughout the day.
I would like to know if these are "normal" side effects of the first few weeks and they will be gone once my body adjusts to the medication or they are more likely to remain. I wouldn't like to discontinue it as I sleep very well on it but the physical anxiety and the chills are very annoying.
I also suffer from Anxiety and I've been taking Escitalopram for that, but my anxiety was completely under control until I started Quetiapine. Please let me know your experiences 🙏🏻
