Are there any serious detrimental health effects from depriving oneself from sleep for two days?

Don't ask why I would do such a thing, I know it is stupid. So, how detrimental to my health would two days of sleep deprivation be.

Sleep deprivation can affect mental heath...alertness and coordination... and prolonged lack of sleep can cause hallucinations.

People who don't get a good night sleep are more prone to obesity, heart disease, and other diseases.
