Agree, I really don’t think she passed from lack of meds, just sayin”, sorry to say. I think it was more of an abrupt end to her life, but Why?
Cold turkey, stopping Gabapentin can lead to seizures. Blood thinners, probably take a while to cause an issue. Pacemaker would still work if she is alive( small shock if heart needs it, to regulate ) just not recording data to phone ( left behind).
I don’t remember if she is diabetic? Lack of insulin can be fatal for some, in a few days…
She was on meds that were very common for an elderly in “good” health. IIRC, She did not need major drugs, ie for cancer.
Doctor’s daughter here, we talk health, meds, so general knowledge here only.
