Insomnia became a real problem for me, because I couldn't get a good rest, and I felt exhausted during the day. I read on https://ways2well.com/blog/can....-hormone-imbalance-c that it could be related to hormonal imbalance. I went to the doctor, took tests - it turned out that I had a low level of serotonin. After adjusting my diet and taking medications, I began to fall asleep quickly and calmly again.
