One post just stood out, And I felt compelled to give a scientific answer.

I wish to lose the need for food, sleep, water, etc. Needs which make humans weak as a race.

It's also what makes them from dieing the most painful death in the universe.
That's wrong, sorry. Needs are what humans where created with, and if Leanardo Da Vinci is correct, Everything is perfect as it was created. So basicly, you'd be making yourself imperfect. Some people don't understand that like every other creature on earth, humans need imput. It's a universal way of survival that has worked forever and will continue to. There isn't any reason whatsoever to do that.
That loss of imput would make you starve almost to death, be insomniac constantly, and be dehidrated. Your body would be feeling a massive amount of pain for about 2 straight weeks, trying to adjust to the massive change in function, in which you might kill yourself.
If that happened you'd be a completely self-sufficiant being, thereby being deemed a completely diffrent race. Of course, for obious scientific reasons you would never be able to breed with other humans, ever; and therefore seince you where the only one fitted with this gift, die out in approximately 80 years. You'd also probably be taken as a test subject in some sort of lab so that popular authorities could copy your genes and, as they always do, abuse them in some way like they do every other abnormality they come across.
Whoo!

I wish to lose the limits of my mental powers. I would be able to memorize it in just a glimpse. Learn to live forever. Enhance my self. Become God.

Oh another answer! Wonderful!
Ahem.
"Live Forever"
What would happen is...
You would be very happy for about 3 years, and then realize the abomination of yourself you have created. You would start to think what would happen in 300 years? Would you be alive? Yes. You would be alive, and through the most dreadful emotion ever, boredom, be the most depressed person ever to live. You wouldn't be able to die- even if you wanted to. Basicly, living forever IS A HORROR BEYOND BELEIF
So that's a bad idea, basicly.
"I wish to lose the limits of my mental powers."
A quote from Halo:
"All AI's sufficiantly think themselves to death after a functional life of 7 years. Seince they are so intelligent and creative, It would basicly be the same as if a human would be thinking so much, he would stop sending required functions to the heart and lungs, focusing on memory space. With this, It would die due to its own thought pattern."
This is the exact same thing that would happen to you, only faster.
"Become God."
If you where God, you would have to handle so much, every day, every single person on earth to deal with- prayers coming so fast your brain could barely handle it...
People see "God" as a hugely good thing. It's not, it's just more daily jobs for you to do; more occupation, more people to deal with.
So yeah, there's your answer. Happy to assist you.
