Spiked Depression….

Because of the medication that i take I’m not suppose to have any caffeine. so when i go to college i drink plenty of energy drinks because it’ll boost up my energy to raise my mood til it dies down then its worse. i am always so tired the day after school that  i dont have class cus i cant have them to the point where im falling asleep standing up. i heard the giant monsters cenn kill u if more than 2 are consumed i drank way more then the amount of two nd im still here. they also get so addicting. anyone else have the same issue with the caffeine addiction. im not trying to stop just wondering what i can do to rid of the sleepiness.
