Yikes, Arella. Is this from your wrist surgery?
One thing I'd say is to rest but also to move around. Lying in bed for days can be very debilitating in itself. So, a bit at a time, move, rest, repeat.
Also, getting proper amounts of minerals are as important as vitamins, but I suppose some of them are in vitamin tablets. I'm odd in that I buy, when money flush, some bottled mineral water like gerolsteiner or apollonaris, or less minerally, pellegrino. Those are all bubbly and a lot of people don't like them. I like to get my vitamins et al from food, but like those waters as back
up. A lot of markets don't have any of those, or maybe just pellegrino.
There are local sparkling waters, but they tend not to have much in the way of minerals. The famous Perrier also has relatively low mineral content.

Bananas are famous as quick potassium boosts.
Watch that staph...
