To begin with, most people are hungry an hour after eating Chinese food. It is weird how that works.

And it sounds like you may not be getting enough water, especially with all that sodium in your diet. Dehydration causes headaches and makes you tired.

In general, though, it sounds like something could be blocking the absorption of nutrients. At this point a blood test to determine what you are low on would be a good idea and then you can see if either it is something missing from your diet or being blocked from being absorbed.

Food allergies could also be ruining how you feel. I don't know enough about them, but wheat comes to mind right away and dairy in second place.

Also - not asking what they are at this point - are you taking any medications regularly?

Hoodia works by targeting glucose receptors. It enhances your mood and keeps you from feeling hungry. The kind grown in South Africa is the real deal, but it is cheaper to grow in Asia. If it is grown in Asia it doesn't work.
