A can of soda typically contains about 30 to 50 milligrams of caffeine, depending on the brand and type. This amount can provide a temporary boost in alertness for about 1 to 3 hours, as caffeine takes effect within 15 to 45 minutes and its stimulating effects can last several hours. However, the duration of wakefulness can vary based on individual tolerance, metabolism, and overall caffeine consumption.
