I seem to get a strange feeling in my head approximately 30 mins - 1 hour AFTER eating some meals. It is generally accompanied by some bloating in the stomach. I assume this is due to a weak digestive system backflushing, which is circulating toxic blood to my head - Could you give a more SCIENTIFIC answer- if there is one? I suppose you would recommend following a better lifestyle (from the "key to...) but it is hard in today's world. I think following 50% of the IDEAL DAILY ROUTINE is good don't you? I try to get to sleep around 10:30pm as you said this is THE MOST beneficial health requirement.
I don't know if this is brainfog, or food allergies or what....
