dizzy!

I dont know what wrong with me but for some reason, i felt dizzy all the time. I am not pregnant for sure. Could it maybe my eyes? or maybe i dont have much sleep. whatever the reason is, i dont really like this feeling at all. i feel like i am having a morning sickness but as what i've said, I am not pregnant!. i just maybe need some rest and spent a little with with my computer. I maybe give it a shot and see if it helps. I am wearing my eyeglasses right now and so far its not helping at all.:(
