What an adventure! Best of luck to your husband. And for you, I have 2 words--YOGA PANTS! When I recently had an epidural they told me to wear elastic waisted pants. I had to think if I even owned any other kind.
It is my understanding that the immunosuppressants we take (one in particular, but I don't remember which, offhand) leach magnesium from our bodies, so I am not surprised that you might need super duper IV supplementation. I take OTC magnesium supplements, and my Mg level is just barely in the normal range, so with you having a double tx, it makes sense that you may need more magnesium. Anyway, I hope you get your IV treatment sooner rather than later. Do you anticipate having this treatment regularly?
Husbands! smh What are we suppose to do? It's hard. I can somewhat relate to the issue of attire. My husband went to the hospital with only the clothes he was wearing, a tee-shirt and pair of shorts. Nothing else. Didn't pack a bag. That's what I call the 3 P's; pizz poor planning. And since we are without a car right now I cannot very well take him anything AND I should not be around hospitals. At least yours wears a cape.
