asthma
"I have a history of anxiety. I was prescribed Singulair because I have been experiencing the feeling of not getting a satisfying breathe. I've been taking big deep breathes and yawning a lot, with a slightly heavy feeling in my chest.After taking the Singulair two nights, I woke up with a slightly racing heart. This continued to happen every night after, but it wasn't so bad that I felt the need to stop. Then one night, I had had a couple of drinks, then took the medicine a couple hours later and went to bed. I woke up very bundled up, so I was overly hot. My heart was racing like I had been running, the overly hot turned to ice cold, I was covered in sweat, and I ended up vomiting. I will never take it again."
