A year ago, my doctor recommended that I take Petril 20 if I felt anxious. I took a few tablets, and then I didn’t really need them anymore. But today, after hearing that someone I’m very close to is on their deathbed, I’m feeling the same way I used to feel back then. I took one tablet because it used to make me feel relaxed, but right now it doesn’t seem to be working. I’m still feeling tightness around my chest and throat.
