I have been drinking coffee and other energy drink type stuff for like 2 years now, and I am wondering, is it possible to become immune to caffeine? The other day I tried this energy drink called "Bawls" which is supposed to be like the most caffinated drink out there, and I didn't really feel any effects. I know energy drinks are super bad for you, and I really dont drink them that often, but I drink coffee pretty much every day, and it seems like all it does is give me the jitters. Maybe I should stop drinking it all together...
