Why am i tired all the time even though i get plenty of sleep and am taking a multivitamin daily?

Eventhough you are not a real vegetarian and are still takin in some protein you might not be getting enough to satisfy the recommended daily allowance related to your height and weight. Perhaps you aren't getting enough sleep, are sick, anemic, or stressed out? Perhaps you aren't taking enough water or exercising. It is best you go to your doctor and see what he recommends. And just because you take a multivitamin doesn't mean you won't get sick or have all the energy you need.

maybe you not meant to be vegetarian or you lacking in certain nutrients

One of my teachers is a veagan and he had to have a pacemaker installed because his heart rate was too slow. I'm sure there's a connection to what you're experiencing. Eat more meat!!!

Maybe try drinking more water? I think dehydration can cause tiredness. Also, be sure that you're getting enough protein. I think an easy mistake to make becoming veggie is to replace your typical meaty meals with other carby or starchy foods. That was a mistake I made, anyway.

possibly Chronic Fatique Syndrome.

maybe you aren't getting the nutrition you should be

because you're too lazy and you keep set your mind to sleep. okay. next time, set your mind to positive thinking.

You need protein, and not just the stuff you get from vitamins. Eat a steak or some chicken. Or maybe you're depressed, it's hard to say...

You are probably lacking in iron. Id go to the doc and see if this is true. Try adding proteins to your diet such as beans, nut and seeds, Peas, beans, lentils, Grains, cereals, rice and wheat protein, tofu, etc... Please don't do this on the fly, go read up and learn before you harm your body. Good Luck
