I understand you. Taking medication seems to be really scared for me as well. I would suggest some natural product to you what I have been used and it really help me to take breath easity. Eventually, I decide to do some business on it because I would like to help people to escape from medicines.

i'm having the same problem since few days. It's like I can't take deep breath (only during day) most of the time. It feels like i'm going to choke. I am seeing a homeopath since a while for my anxiety and pre-menopausal symptoms. Do you feel anxious or have you been stressed lately?
I know that women going through peri-menopause, experience sometimes that symptom. I'd go to your doctor and inquire, if it's not anxioety related.
