Firstly, I hope you meant to say 13 and not 3 years old to start drinking coffee, even 13 is pretty young. But regardless, the fact that you already know you are sensitive to coffee in the first place, may interfere with how your pre-workouts work.

You may seem extremely light headed, dizzy, very fast heart beat, etc.

If you need your coffee to get you through your day (like myself) than I suggest looking for other alternatives that are caffeine free. Might help with the jitters, but still help you get a great pump!
