Your diet sounds terrible. My husband and I have been vegetarians (almost vegan) for the last three years. I have better endurance than ever.
The only supplement we use is B12, even though most foods are already fortified with it. Visit
Vegpeople.com for more advice.
I've met people (two, to be exact) whose health leaves a lot to be desired in spite of being vegetarian because they live on pizza, soft drinks, and other junk food. There are reasons it's called "junk". Eat vegetables, eat fruits, chocolate covered frozen bananas, soy milk, soy yogurt (peach, raspberry, vanilla), drink plenty of water, and most important of all, buy a good vegetarian cook book. I've been cooking a new recipe every other day using a book called
"1000 Vegetarian Recipes From Around the World". As a result, our diet is far more varied and flavorful than before becoming vegetarian. At this rate, it will take me nearly five years to cook everything in the book just once! Whenever people ask me "but... what do you eat?", I just point to my gargantuan cook book. :wink: Before buying it, I didn't really know where to start.
So, lay off the refined sugars and flours, get informed, and get better!
