Can you get the doc to double the dosage so you can sock some away? That's what I've done with my prostate meds.Many people have no thyroid gland and must take Synthroid (or levothyroxine) daily. This reality begs the question: Given a cataclysmic event, where traditional pharmaceuticals can no longer be obtained, what to do? Are there herbs, other plants, fungi, or foods, say, large animal brains or thyroids that one could consume to sustain their life? My former endocrinologist said, in essence, enjoy the month or two you would have left…then you’re done.
