I'm Slow And Mentally (Not Physically!) Tired Quickly, What Can Be The Reason, And Any Remed
First of all I am a very slow person. I am slow to think, slow to do stuff, slow to eat. I have always been like that. As a child at dinner, once everyone was finished eating, I was still eating for another hour. Now I am 35 years old and I'm still the same. Slow not only at eating, but everything. I am only a fast walker, I walk maybe 50% faster then other people, but almost everything else in life takes me maybe twice as much time (normal things, which everyone does, like getting dressed, eating, etc. Its hurting my life tremendously, as after I subtract from 24 hours the time I sleep, the time I need for daily body maintenance tasks like eating, dressing, showering, brushing teeth, shaving, there is very little time of the day left for me. I often resort to just skipping things, not showering, recently I grew I beard, just to have more time of the day left. I can do everything very precisely, everything takes me a lot more time then for other people.
Second thing I get mentally tired rather quickly and need a lot of mental rest often and for extended periods, just to be able to use my brain properly again. Many times during the day I do not feel physically tired, I feel physically very energetic, but I can't seem to just use my brain any more, I need to take at least half an hour when I don't use my brain too much, like walking in nature, sitting on grass, etc, and then I am good to go again.
This all leaves very little time during the day when I can actually do useful stuff. Out of 24 hours of the day, I maybe have roughly 4 hours where I am actually working mentally properly and can do stuff. The remaining 20 hours is body maintenance tasks (sleep/rest/cook/eat/wash/poop/revive). I need to revive mentally (by doing nothing for 5-20 minutes) even after washing dishes, eating or pooping! I'm NOT physically tired, I just feel like I can't think more even about simplest stuff until I rest. Its not something new, I've been like that a long time as I can remember, but only now I start thinking more and more that maybe there is something fixable in my body that can at least improve that significantly. I feel like this is not normal, and definitely sub-optimal. Eating Paleo since April 2012 and Bulletproof since June 2013 didn't fix it. Taking all the supplements I have listed in my post signature didn't fix it - as you see I take almost every useful mineral and vitamin, besides eating a nutrient-rich diet, full of pastured beef, wild fish and organic vegetables. I even eat liver once a week. Still it didn't help in the mentioned problem.
Anybody can shed any light on what it can be, does it ring a bell to anyone? Like you have saw or heard about this somewhere already? Possible solutions, and possible pointers to functional medicine experts who can analyze my body more thoroughly to find the causes and solutions? Any lab tests I could do?
