I am not sure if this is related to menopause or withdrawal -or maybe both.   I experience irregular ectopic heart beats - they don't cause dizziness or pain, i just feel them as a thump thump. It is not tachycardia - (continual fast heart beat) and it is not related to any anxiety. I thought i would ask here before doing anything else - i have had them off and on over the years but haven't taken a lot of notice about whether or not they were occurring only during withdrawal. The only thing
