I know what it was. I had a mix drink, but I didn't know what it was mixed with. I have a lot of pain trying to deal with guarana and taurine, which are common ingredients in energy drinks. Ever since, I haven't drunk one. But the drink I was told was "mixed" had them in there, but I wasn't told. I get a lot of pain through my body, i shake uncontrollably, and breathe faster. But this time, I couldn't breathe fast, because it hurt to breathe, which is where the people at the hospital made the conclusion that my lungs had collapsed. And there's no one; I live by myself. But I've been at friend's places all week, trying to keep cool during this heat wave. And just for company.
