Hi @lily1943,

I see that @colleenyoung was nice enough to reply to your question on the podcast that was held. Have you been able to answer her? I linked it below in case you are having trouble locating it.

I am sorry that your husband is having such a hard time. Has he been diagnosed with total heart blockage, or are you just worried about the side effects of the medication?
