You are most likely getting dizzy due to staring at the computer screen too long and poor nutrition. That is your body's way of letting you know you are low on bodily resources.
Being an entrepreneur takes a lot out of you because it's a lot of thinking. Thinking drains bodily resources. I have a notion to believe thinking actually burns calories because when I am done working after a few hours, I am STARVING. Even though all I have been doing is sitting at my desk.
When you wake up in the morning, sit outside for awhile and eat breakfast so you can fill up your body with "gasoline" and let your eyes rest before you start working on the computer. After you eat, start work. After 2 hours of work, take a break. Get up and go outside, do a quick exercise routine, and let your eyes rest. Then work for another hour. After working for an hour, take a break and have lunch outside so you can rest some more and fill up with more gasoline. Then get back to work for another 2 hours. After 2 hours, take another break outside to let your eyes rest, and have a snack. Then get back to work again for another hour. After an hour, eat dinner, and rest for the rest of the evening. You should probably even take weekends off as well, and do not look at the computer on the weekends. Let your eyes rest.
Try to keep your daily schedule consistent and as if you were working a regular day job. For some reason, we entrepreneurs like to work, and work, and work, and work, without taking any breaks because we are too focused on making our dreams come true. We forget to eat and don't want to sleep. Eating and sleeping are doing nothing but holding us back from our dreams! Lol.
But we need both food and sleep so we can keep going. So cut out the coffee and Red Bull. Those are horrible for the body. You will have to load up on green vegetables, fruit, and hardy meat in order to be able to perform at high levels like we want to.
Your body is like a Ferrari. It will only accept the highest quality of gasoline in order to perform at the levels it was intended to. Imagine if you put some cheap "Regular Unleaded" gas in your Ferrari.



It would not run anywhere near the way it's supposed to, and it would probably start making strange noises as you drive. So don't put cheap gas like Red Bull and caffeine into your body. That is synthetic gas that won't get you very far.
I normally listen to classical music, or a rainstorm, or birds chirping while I work. It keeps the energy around me clean and "tranquil".
