woke up gasping for air...felt as if I had cotton in my throat. After gasping for air and coughing for about 15 minutes...my airways cleared. NEVER had this before. could this be an adverse reaction to new pills i got today from amazon? greenceutics green pura (back of bottle says not evauluated by FDA) and flexoplex. Also at something new hot and spicy cheezits. My breathing is fine now...still feel like a piece of hair is stuck in my throat.
