Hi,
I am posting this questions in this category since I can't find the better one.
Every day, after about 3 pm in the afternoon, I feel very tired and weak, my neck is hurting a lot and eyes are feeling like they are burning. Generally, I feel like out of energy. I feel this everyday but when the evening is starting (at around 7 pm) I again feel very refreshed like in the morning and all pain is gone. I know it sounds funny, but for me it is not because I am a student and this is not good for me since I can't study and because of that I feel very demotivated. Sorry if my English is not good, looking for some good advice so I can stop this tiredness! Thanks!
