Thank you, White Tiger, for replying so quickly. Would GERD explain the heart palpitations? Also even when upright I feel like my throat is absolutely stuffed, and I feel a bit weak, floppy and dizzy. I am so grateful to you and others who are helping me. I do get very anxious if I think something is wrong with me, but I shy away from going to the doctor's as I have no faith in them whatsoever.
