I really do not think feeling dizzy and blurred vision is a good thing and agree with the others in saying I think you should go to a dr. I will also offer this info:

I just began reading the book by Nancy Clark Cyclists Food Guide. In a way it is basic common sense, but it is giving me good ideas, for one, there is no reason to ever go hungry. Here is one is their food pyramid:

the numbers are servings per day:
6-11 whole grains; 2-4 fruit; 3-5 vegtable; 2-3 protein; 2-3 low fat dairy; saturated fats and refined sugar use sparingly.

I know for my weight I would have the lowest #.

She gives an example for one day which is a very realistic one and not difficult:

Breakfast: Cereal; banana; milk
Snack; pretzels; yogurt
Lunch: bread; orange; vegetable soup; peanut butter
Dinner: spaghetti; tomato sauce, broccoli; cheese; ground turkey
Snack: popcorn; juice

She gives lists of food for all catagories, just a wealth of ideas. Of course you have to be honest with portion control and how many servings for your body type.

The last chapter is called the In Pursuit of Thinness. I did not get this far, but at a glance I see this: appropriate eating + regular exercise = appropriate weight. We all probably know this already, but keeping it in mind is sometimes difficult.

I think I might actually gain a couple of pounds by this, but I had lost more than I planned to. Then again, I might have more energy for my cycling and I just might stay the same. I just think the whole concept is a good one and thought I would share it.
