Energy Drinks Part 2

I am still in the experimental stage, today I tried 2 energy shots. They taste terrible, and 2 different kinds do not go together. One tasted like coke syrup, the other, cough medicine. Gross. I felt like throwing up! Luckily, I didn't. My heart didn't race, I didn't have a heart attack or palpitations. I did clean the upstairs of my house, but not in record time, and I can do that without energy drinks. I still feel a bit pukey 2 hours later. Maybe a little shaky too. Maybe I didn't notice the shakes when I was cleaning. Will I do that again? I highly doubt it. The puke factor was way too high, the energy boost not enough. I think this experiment might be over. So in conclusion, I think I may be immune to caffeine after all. If I crash hard later, I let you know. I still have 2 shots left, so if I need to throw up anytime soon, I guess I know what to do with them!
