How much coffee is equivalent to a wakeup pill?

Doctor's Response: To evaluate the safety of your caffeine consumption, you need to estimate the amount of caffeine consumed. Moderate and safe consumption is estimated at a maximum of 300 mg of caffeine per day. I recommend that you check the amount of caffeine contained in the Redbulls in order to be able to calculate your total caffeine consumption by adding a wake-up pill. The side effects related to an overdose of caffeine are: increased nervousness, trembling, insomnia, increased blood pressure and heart rate (pulse), etc. If you have any further questions, do not hesitate to contact me.
