Can't figure it out (vegetarian)
I have been a vegetarian for 2 years now, and I have been unhealthily tired for the last 1 of those years. It has come to the point where I sleep through classes that start at 3:30 pm, barely show up to work, and have problems completing assignments/studying. I have been to a physician and had blood tests for TSH, zinc, b12, d, and pretty much any other thing that could cause tiredness. I get my daily values of ascorbic acid and iron, easily meet my requirements of grains, vegetables/fruit, and get my protein from a wide variety of sources (nuts, lentils, flax, grains, soy, as well as animal products like eggs and yogourt - I'm not vegan yet). For the past year I have spent time experimenting with different levels of these foods, so I know I'm not allergic to soy, for example. I exercise regularly, althought not as much as I used to before this lame problem.
So I'm feeling quite helpless/hopeless at this time, and any tips on where to look next for answers would be appreciated.
