question: Lately I have had dizziness, nausea and a occassion sudden gasping for breath. I have also had some palpitations. I went to My PCP about three weeks ago and was given meclizine for the dizziness.  They did blood work and a EKG but nothing pointed to these issues.   I am a 47 year old female with blood pressure well controlled by Avapro.  I am on low estrogen birth control pills. Any ideas?
