I had a similar condition due to cervical osteochondrosis. I started to sleep more, but I felt constantly tired. It was difficult for me to concentrate on something, it led to problems at work, I became irritable and it spoiled my relationship with my family. I went to the doctor, I thought that the reason was that I lacked some vitamins, but it turned out that due to the deposition of salts in my cervical spine less blood flowed into the brain and this led to this condition. I went for a massage, drank the pills that the doctor prescribed for me and put a heating pad on my neck before going to bed (by the way, this is a good way to relax and fall asleep faster). The treatment took about 6 weeks, but I began to feel better after the third massage session. Now I try to take more care of my health, I do exercises for the neck and back, I use a special pillow that keeps my head in the right position and reduces the load on the neck muscles. Here https://ortorex.com/p/latex/ there is a video where it’s described in more detail how the shape of the pillow affects sleep. I also try not to eat salty foods and drink only filtered water. I know that any health disorders strongly and sometimes unexpectedly affect our condition and this can affect our actions, so if a person suddenly changes his behavior, this is the first signal to visit a doctor.
