Hi all, I've had anxiety for at least 15 years now (since high school). Just recently, after 6+ years on klonopin, I've been weaning off. It seems like right around the same time, I've been getting random bouts of feeling out of breath, heart beating fast, probably high blood pressure. Usually I hyperventilate, can't catch my breath, end up gagging or throwing up. The funny thing is, I don't psychologically feel anxious during these times. More annoyed that this is happening. 
Does anyone else experience this? Could it be linked to weaning off of klonopin? Is it worth it to see a doctor about or will it just get chalked up to anxiety?
