I have good energy in the morning , and sometimes later evening. However after lunch I always feel very tired so much so concentration is difficult and will to get things done is a struggle. I think if i had the time for it and it was quiet enough i could nearly sleep in the afternoon. It is even on days off and I actually now think to myself I will do this and that in the morning because I will have more energy for it. Does anyone have this and how did you overcome it?
