Question: I was working today and I just went blank. I couldn’t understand what the words were I was reading. It just felt like I was blank. My right hand was shaking. Not on drugs. However I do take Niacin and Creatine in a prework regimen for working out. I may have taken more than I needed today., because I felt really jazzed and hyped after my workout this morning. Never blacked out or anything. 5 minutes later I was fine.

Brief Answer:
It does not seem to be side effect of the drugs you take, detailed explanation below

Detailed Answer:

Thank you for asking at "Ask a Doctor" service. I carefully went through the query.
It does not seem to me that the symptoms you had are related to side effects of the drugs you are taking. This is first because they do not seem typical of side effects of these drugs and also because if it is side effect of the drugs it would not last only a few minutes but would be longer or repeat several times during the time of the effect of the drug in the body (for hours).

There are a few things that might be responsible for the episode.

The symptoms seem to be related to a self limiting condition of your body, sometimes it is related to stress, sometimes it is related to vasovagal syncope (especially if you have been standing long or not eating or drinking well or even eating too much at a time might cause some similar symptoms directly after the meal). The reason why these self limiting and not serious conditions are considered is because the episode was single and lasted only 5 minutes and you turned to your normal after it.

If the episode repeats or lasts more then half an hour or you do have symptoms left after the episode other important conditions should be considered and rule out. One of them would be simple partial seizures which consist of shaking of certain parts of the body without completely loosing the consciousness. Other issues to rule out is the blood pressure, glucose levels, electrolytes in blood and basic metabolic profile might be good to check.

To conclude I would say:
- because the episode was single and short and you did not have symptoms left after it, no drug use and as I noticed no chronic conditions you are treated for, very likely this is a self limiting issue and you will be just fine and nothing to worry (vasovagal syncope or stress/anxiety might be the cause).
- if the episode repeats or lasts for more than half an hour or you have symptoms left after the episode (even presence of one of these) shows that you might need to see your doctor to rule out other important conditions and have the following tests and examination:
a good and thorough physical examination (including listening of the heart and lungs), blood pressure, an ECG (to check the heart rhythm and other possible findings)
CBC and ERS (for anemia), TSH (for the thyroid), glucose levels, lipids, creatinine and electrolytes (for the kidney function), ALT, AST, bilirubin (for the liver function), possibly an EEG (to check the brain waves and rule out seizures)

I hope I have answered your query. Let me know if I can assist you further.
